Yield & timing
-
Servings: 6–8
-
Prep time: 5–10 minutes
-
Cook time (air fryer): 12–18 minutes (depends on pan size and model)
-
Total time: ~20–30 minutes
Ingredients
-
6 cups cubed day-old bread (about 6–8 slices, cubed)
-
2 cups diced cooked ham
-
2 cups shredded cheddar cheese
-
Optional: butter or cooking spray for greasing the pan
-
Tip: Use slightly stale bread — it soaks up any moisture better. If bread is fresh, toast the cubes briefly in the air fryer (3–4 minutes) to dry them a little.
What you’ll need (equipment)
-
Air fryer with a basket or air-fryer-oven large enough for a small baking pan
-
An oven-safe pan that fits your air fryer (an 8×8-inch square pan or a 7–9-inch round pan works best). If your air fryer is small, divide into two smaller pans and cook in batches.
Step-by-step air fryer instructions
1. Prep the air fryer and pan
Preheat your air fryer to 325°F (163°C) for 3–4 minutes.
Lightly grease an 8×8-inch oven-safe pan or spray the air fryer basket (if using a perforated pan) with cooking spray.
2. Layer the casserole
-
Spread the 6 cups cubed bread evenly in the greased pan. Press down lightly so the bread forms an even layer.
-
Scatter the 2 cups diced ham evenly over the bread.
-
Top with 2 cups shredded cheddar cheese, spreading it so the entire surface is covered.
3. Cook covered (initial)
To prevent the top from over-browning while allowing the interior to heat through, cover loosely with foil (use a small rack if your air fryer has low clearance). Cook at 325°F (163°C) for 8–10 minutes. This warms the filling and helps the bread soften.
4. Finish uncovered for browning
Carefully remove the foil and continue cooking at 350°F (177°C) for 4–8 minutes, or until the cheese is fully melted, bubbling, and the top is lightly golden. Keep an eye on it — air fryers brown faster than ovens.
5. Rest and serve
Remove the pan from the air fryer and let the casserole rest 3–5 minutes so it sets. Slice into squares and serve warm.
Quick notes for success
-
Pan size matters. If your air fryer space is small, split the mixture between two smaller pans and reduce cook time by a few minutes.
-
Don’t skip resting. Resting helps the casserole hold its shape when served.
-
Cheese melt vs. browning: If the top browns too quickly before the center is hot, lower the temp to 320°F and extend cook time slightly.
-
Crispier top: Reduce the cover time or finish on high (350–375°F) for a couple of minutes — watch carefully.
Variations & upgrades
-
Eggy strata: Whisk 3–4 eggs with 1 cup milk and pour over the bread before adding ham and cheese. Let sit 10–15 minutes to soak, then cook as directed.
-
Vegetable boost: Add 1 cup sautéed mushrooms, bell peppers, or spinach.
-
Different cheeses: Swap cheddar for pepper jack, Swiss, or a blend for different flavor profiles.
-
Herby touch: Sprinkle 1 tsp dried chives or 1 tbsp fresh parsley before serving.
-
Make it lighter: Use low-fat cheese and lean diced ham or turkey.
Make-ahead, storage & reheating
-
Make-ahead: Assemble in the pan, cover tightly, and refrigerate up to 24 hours. Cook straight from fridge; add 3–5 minutes to the cook time.
-
Refrigerator: Store leftovers in an airtight container for 3–4 days.
-
Freezer: Portion and freeze for up to 1 month (thaw overnight before reheating).
-
Reheat: Warm slices in the air fryer at 320°F for 3–5 minutes until heated through, or use microwave for 60–90 seconds.
Serving suggestions
-
Serve with a fresh green salad or fruit salad for a balanced brunch.
-
Add hot sauce, salsa, or a dollop of sour cream for extra zing.
-
Great packed for lunchboxes — pairs well with a side of pickles.
