Most buyers should take the Breville BOV900BSS Oven Air Fryer. Its listing gives you a bigger interior, 13 cooking functions and a dehydrate setting, and those three things decide more meals than anything else here. Take the Breville BOV860BSS Oven Air Fryer instead if your counter space is tight and 11 functions already cover how you cook. Both are countertop ovens with air frying built in, so the real question isn’t which one cooks — it’s which one fits your kitchen and your week. Buyers get this wrong by counting features on the box instead of measuring the space on the counter and picturing the food they actually make. The rounds below run on the points that change that decision: what’s included, what each one holds, what it does well, how it’s meant to be used, and how long it’s covered. Every claim comes from the seller’s own listing, and nothing here is a hands-on test.

Round wins don’t add up to an overall winner on their own. Two rounds here are genuine ties, because both listings describe the same convection system, the same display and the same interior light. The round most buyers should weigh heaviest is interior space, since the two listings differ most there.
Meet the BOV860BSS and BOV900BSS Ovens
Breville BOV900BSS Oven Air Fryer — the larger, fuller-featured one
The BOV900BSS listing leads with capacity and function count. It describes a 16 x 13.5 x 7 inch interior, room for 9 slices of bread, a 14 pound turkey, or slow cooking with a 5 quart Dutch oven, and it says the oven fits most 9 x 13 inch pans and 12 cup muffin trays. The Element iQ System with 5 independent quartz elements and digital PID control is the cooking engine behind all of it. Its 13 functions include Dehydrate, which the listing says handles up to 4 trays at once. This one is aimed at people who want one countertop appliance to cover roasting, air frying and drying food.
Breville BOV860BSS Oven Air Fryer — the compact, simpler one
The BOV860BSS listing leads with the same cooking technology in a smaller footprint. It lists the same Element iQ System with 5 independent quartz elements and digital PID temperature control, and the same super convection that the listing says can cut cooking time by up to 30%. Its interior is 13.5 x 11.5 x 5.5 inches, with room listed for 6 slices of bread, a 13 inch pizza, a roast chicken, a 9 cup muffin tray, or slow cooking with a 4.4 quart Dutch oven. It offers 11 functions, dropping Dehydrate from the set. This one suits smaller kitchens and smaller households.
Round 1: What you actually get
This round decides how much work a single appliance takes off your counter. The BOV900BSS listing names 13 functions: Toast, Bagel, Broil, Bake, Roast, Warm, Pizza, Proof, Air Fry, Reheat, Cookies, Slow Cook and Dehydrate. The BOV860BSS listing names 11: Toast, Bagel, Broil, Bake, Roast, Warm, Pizza, Air Fry, Reheat, Cookies and Slow Cook. The gap comes down to Proof and Dehydrate, and both matter more than they sound. Proof is what lets you raise dough for bread in the same box. Dehydrate is what turns fruit, herbs and jerky into a project you can actually finish. If you bake bread or dry food, that gap is the whole round.
| Breville BOV900BSS Oven Air Fryer | Breville BOV860BSS Oven Air Fryer |
|---|---|
| 13 cooking functions listed | 11 cooking functions listed |
| Dehydrate up to 4 trays at once | Not listed |
| Proof function listed | Not listed |
| Interior oven light listed | Interior oven light listed |
Round winner: Breville BOV900BSS Oven Air Fryer — adds proofing and dehydrating to the same function set.
Round 2: Interior space
Space is the round you can’t work around later. The BOV900BSS listing gives a 16 x 13.5 x 7 inch interior and says it holds 9 slices of bread, a 14 pound turkey, or a 5 quart Dutch oven for slow cooking. The BOV860BSS listing gives 13.5 x 11.5 x 5.5 inches and says it holds 6 slices of bread, a 13 inch pizza, a roast chicken, or a 4.4 quart Dutch oven. Notice the height difference too: the BOV900BSS lists 7 inches of interior height and the BOV860BSS lists 5.5 inches. If you cook for a family or batch-cook for the week, the larger interior is the difference between fitting everything at once and running a second batch. If you are cooking for a couple rather than a crowd, the smaller box does the same job in less counter space.
| Breville BOV900BSS Oven Air Fryer | Breville BOV860BSS Oven Air Fryer |
|---|---|
| 16 x 13.5 x 7 inch interior listed | 13.5 x 11.5 x 5.5 inch interior listed |
| 9 slices of bread listed | 6 slices of bread listed |
| 14 pound turkey listed | Roast chicken listed |
| 5 qt Dutch oven listed | 4.4 qt Dutch oven listed |
Round winner: Breville BOV900BSS Oven Air Fryer — bigger listed interior and larger capacity examples across the board.
Round 3: Air fry and convection
This is the round both ovens were built around, and the two listings describe it in almost the same words. Both name the Element iQ System with 5 independent quartz elements, and both say smart algorithms steer power where it’s needed. Both list digital PID temperature control that the listings say eliminates cold spots. Both describe super convection, with the listings claiming it can reduce cooking time by up to 30%, and both list a dedicated Air Fry setting for fries and wings. The BOV900BSS listing adds a detail: a 2 speed convection fan, super and regular, for more control. Neither listing separates the two on convection, and the fan speed is a control option rather than a result.
| Breville BOV900BSS Oven Air Fryer | Breville BOV860BSS Oven Air Fryer |
|---|---|
| Element iQ, 5 quartz elements | Element iQ, 5 quartz elements |
| Digital PID temperature control | Digital PID temperature control |
| Super convection, up to 30% faster | Super convection, up to 30% faster |
| 2 speed convection fan listed | Not listed |
Round winner: Too close to call — both listings describe the same convection system and air fry setting.
Round 4: Living with it day to day
This round is about the small stuff you touch every time you cook. Both listings describe an LCD display that shows the cooking functions and tells you when pre-heat is done, then counts down the cooking time. Both describe an interior oven light that switches on automatically at the end of the cycle, and can be turned on any time to check progress. Both listings also say the ovens use replaceable componentry, like a traditional large oven. The BOV900BSS listing ties its display to 13 functions and the BOV860BSS to 11, so the panel on the larger one has more to scroll through. Neither listing describes cleaning, crumb trays or rack positions, so this round stays on what’s stated.
| Breville BOV900BSS Oven Air Fryer | Breville BOV860BSS Oven Air Fryer |
|---|---|
| LCD display with pre-heat indicator | LCD display with pre-heat indicator |
| Interior light, auto on at cycle end | Interior light, auto on at cycle end |
| Replaceable componentry listed | Replaceable componentry listed |
| 13 functions on the display | 11 functions on the display |
Round winner: Too close to call — the same display, light and replaceable parts appear in both listings.
Round 5: Coverage and support
This round asks what happens after the first year, and it’s where both listings go quiet. Neither listing states a warranty length, so there’s no honest way to separate them on coverage from the pages themselves. What both do say is that the ovens use replaceable componentry, like a traditional large oven. Because the listings don’t give a term, the practical step is to check the manufacturer’s own warranty page before you buy, and to keep the receipt. Treat this round as a tie on the listed facts and a question to settle at the source.
| Breville BOV900BSS Oven Air Fryer | Breville BOV860BSS Oven Air Fryer |
|---|---|
| Warranty length not listed | Warranty length not listed |
| Replaceable componentry listed | Replaceable componentry listed |
| Breville brand | Breville brand |
Round winner: Too close to call — no warranty term appears in either listing to compare.
What This Comparison Can’t Settle
Two listings tell you what a seller chose to say, and that’s the ceiling here. They don’t tell you how either oven behaves after a year of weekly roasts, or how the door feels on the hundredth open. They don’t tell you how the seller handles a repair request, or how quickly parts arrive. And they don’t tell you the one thing that decides most kitchens: whether the machine earns its counter space once the novelty wears off. Before you buy, it’s worth checking the manufacturer’s own support pages for the terms the listings leave open, including the warranty that applies to countertop cooking appliances.
- How does the oven hold up after a year of regular roasting and air frying?
- How does the seller handle a warranty claim, and how fast do replacement parts arrive?
- How even is the browning on the top rack compared with the bottom rack?
- How easy is the interior to clean after a greasy air fry session?
The Final Call
Take the Breville BOV900BSS Oven Air Fryer if the earlier rounds describe the way you cook. You bake bread, you dry fruit or make jerky, you roast a whole bird, or you feed a family from one tray. The 13 functions, the proof and dehydrate settings, and the larger listed interior all point the same way, and both listings describe a 2 speed convection fan. It’s the one to pick when you want the countertop oven to cover roasting, air frying and drying food.
Take the Breville BOV860BSS Oven Air Fryer if your kitchen is short on counter space and your cooking is simpler. It lists the same Element iQ system, the same PID control and the same super convection with the same up-to-30% time claim, so the core cooking is described identically. It still handles toast, pizza, roast chicken and slow cooking in a 4.4 quart Dutch oven. What you give up is the dehydrate and proof functions and the larger interior, and for one or two people that’s a fair trade.
If you still can’t decide, ask which single dish you make most often, and pick the oven whose listed capacity covers it in one batch.
Frequently Asked Questions
Is the Breville BOV900BSS Oven Air Fryer too big for a small kitchen?
It depends on your counter, not the oven’s reputation. The listing gives a 16 x 13.5 x 7 inch interior, which is the cooking space, not the full footprint on your counter. Measure the spot you have and compare it with the appliance dimensions before ordering. If the space is tight, the BOV860BSS lists a smaller interior at 13.5 x 11.5 x 5.5 inches and may sit more comfortably.
Can the Breville BOV860BSS Oven Air Fryer replace a full-size oven?
For many everyday meals, its listing suggests it can. It names Toast, Bagel, Broil, Bake, Roast, Warm, Pizza, Air Fry, Reheat, Cookies and Slow Cook, and lists room for a 13 inch pizza, a roast chicken and a 4.4 quart Dutch oven. That covers most weeknight cooking. A 14 pound turkey or a large batch of dehydrating is where the larger BOV900BSS listing pulls ahead.
Do both ovens air fry the same way?
On the listed facts, yes. Both listings describe the Element iQ System with 5 independent quartz elements, digital PID temperature control, super convection that the listings say can cut cooking time by up to 30%, and a dedicated Air Fry setting. The core air fry method described is the same in both.
What does the dehydrate function actually let you do?
The BOV900BSS listing says it can dehydrate up to 4 trays at once across a wide range of foods. In practice that means dried fruit, herbs, vegetable chips or jerky made in your own kitchen rather than bought. The BOV860BSS listing does not include a dehydrate function among its 11, so if drying food is a goal, that’s the deciding difference between the two.
Is the simpler Breville BOV860BSS Oven Air Fryer enough for one or two people?
Its listed capacity points that way. The listing gives room for 6 slices of bread, a 13 inch pizza, a roast chicken and a 9 cup muffin tray, plus slow cooking with a 4.4 quart Dutch oven. For one or two people that covers breakfast, dinner and baking. The larger BOV900BSS makes more sense when you regularly cook for a crowd or batch-cook ahead.
What should I check before buying either oven?
Check three things the listings don’t settle: the warranty term on the manufacturer’s own page, the exact outer dimensions against your counter space, and whether you need dehydrate or proof. Both listings say the ovens use replaceable componentry, like a traditional large oven. For the warranty specifics, look at the official Breville support pages rather than the product listing.
