Breville Smart Oven Pro vs Breville Smart Oven Air: Which Countertop Oven Is Worth Buying?

Finding a countertop oven that can actually replace multiple kitchen appliances isn’t easy, but Breville’s lineup comes remarkably close. I’ve spent plenty of time cooking, baking, roasting, and reheating meals in both the Breville Smart Oven Pro (BOV845BSS) and the Breville Smart Oven Air Fryer (BOV900BSS) — and while they share the same DNA, the experience they offer is quite different.

Both ovens use Breville’s impressive Element iQ System, both sit at 1800 watts, and both can function as dependable everyday ovens. But depending on how you cook, one of these models offers far more versatility and long-term value.

Let me walk you through the differences based on real-world use.

Main Difference Between Breville Smart Oven Pro vs Breville Smart Oven Air Fryer

The biggest difference comes down to functionality and airflow performance.

• Breville Smart Oven Pro: A powerful convection toaster oven with 10 functions, including an excellent Slow Cook mode. Ideal for baking, reheating, roasting, and daily use.
• Breville Smart Oven Air Fryer: Includes all Pro features but adds Air Fry, Dehydrate, Proof, and a super convection fan for crispier and faster cooking. It also has a larger interior, more accessories, and a 2-year warranty instead of 1 year.

Simply put:
If you want air frying + maximum versatility → Air Fryer wins.
If you want a reliable do-everything oven without those extras → Pro is perfect.

Detailed Comparative Review – Design and Build Quality

The first thing I noticed when unboxing these ovens was the size difference.
The Smart Oven Pro feels compact and lighter, making it easier to move or reposition on the countertop. The stainless-steel build is sturdy, and its interior lighting is surprisingly bright for a mid-sized model.

The Smart Oven Air Fryer, meanwhile, is bigger and heavier — and you feel that immediately. It takes up more counter depth and width, but the extra space is put to good use. I could fit a 14-lb turkey, full cookie trays, and even air-fry larger batches because of the added height and enhanced airflow.

If you have limited counter space, the Pro fits better.
If you want an oven that can act like a small conventional oven, the Air Fryer stands out.

Ease of Use

The controls on both models are clean, logical, and fast to navigate.
However, here’s what stood out for me after using both:

Smart Oven Pro Experience

The Pro’s interface is simple. I could move from Toast → Bake → Slow Cook without thinking. It feels like an everyday oven that works exactly how you expect.

It heats quickly, runs quietly, and has consistent temperature accuracy for cakes, brownies, and casseroles.

Smart Oven Air Fryer Experience

The Air Fryer model gives you more to choose from, but it still remains user-friendly. Once I started using Air Fry and Dehydrate, I realized how much more this oven could do.

The super convection fan is noticeably louder but also incredibly efficient. French fries, chicken wings, and vegetables crisped up better and faster than in the Pro.

The added functions don’t feel gimmicky — they genuinely expand what the oven can do.

Performance and Cooking Results

Breville Smart Oven Pro

This model excels in:

• Baking evenly
• Slow cooking meats (4–10 hrs)
• Roasting vegetables
• Reheating leftovers without drying them out
• Toasting bread perfectly

It’s not trying to mimic an air fryer — and you can tell. Foods don’t get that deep, crispy finish that the Air Fryer model can achieve.

Breville Smart Oven Air Fryer

This oven is simply more powerful in terms of airflow and versatility.

What impressed me most:

• Air Fry mode produces a crisp, golden texture without oil
• Dehydrate mode works beautifully for fruit, herbs, and snacks
• Proof mode is ideal for dough lovers
• Super convection reduced my cooking times noticeably
• Roasts develop better browning due to stronger airflow
• Larger items (like whole chickens) fit more comfortably

If you cook often and like experimenting, the Air Fryer model is much more fulfilling.]

Functions and Cooking Modes

Smart Oven Pro — 10 Functions

Toast, Bagel, Bake, Roast, Broil, Pizza, Cookies, Reheat, Warm, Slow Cook

This lineup is perfect for daily use. The Slow Cook is genuinely useful and works like a mini crock pot.

Smart Oven Air Fryer — 13 Functions

Toast, Bagel, Broil, Bake, Roast, Warm, Pizza, Proof, Air Fry, Reheat, Cookies, Slow Cook, Dehydrate

The extra modes (Air Fry, Dehydrate, Proof) turn the oven into a multi-appliance replacement. If you already own a standalone air fryer or dehydrator, this can consolidate everything.

Conclusion: Which One Do I Recommend?

After using both ovens extensively, here’s my honest take:

If you want a simple, reliable, powerful countertop oven for everyday cooking, baking, and reheating, the Breville Smart Oven Pro is more than enough. It’s easier to fit anywhere and does everything a high-quality toaster oven should do.

But if you want real versatility — the ability to air fry, dehydrate, proof dough, roast faster, and crisp foods like a deep fryer — then the Breville Smart Oven Air Fryer is absolutely worth the upgrade.

It performs better, cooks faster, holds more food, and replaces more appliances.
For most modern kitchens, the Air Fryer model delivers far more long-term value.
