Instructions

Cheesy Sausage and Egg Breakfast Casserole for Festive Family Brunch

Step 1: Cook the Sausage

Heat a large skillet over medium heat, crumble the sausage, and cook until browned and no longer pink, about 6‑8 minutes. Drain excess fat, then set the meat aside to cool slightly.

Pro Tip: For extra flavor, add a pinch of smoked paprika while the sausage cooks.

Step 2: Prepare the Custard

In a large bowl whisk together eggs, milk, smoked paprika, salt, and pepper until fully combined. The mixture should be smooth and slightly frothy, indicating air has been incorporated for a fluffy texture.

Pro Tip: Add a tablespoon of Dijon mustard for a subtle tang.

Step 3: Combine Bread and Fillings

Layer the bread cubes in a greased 9‑x‑13‑inch baking dish. Sprinkle the cooked sausage, diced bell pepper, and half of the shredded cheddar evenly over the bread, then pour the custard mixture to soak everything thoroughly.

Pro Tip: Press the bread gently with a spatula to ensure it absorbs the custard.

Step 4: Bake to Golden Perfection

Cover the dish with foil and bake in a pre‑heated 375°F (190°C) oven for 25 minutes. Remove foil, sprinkle the remaining cheddar, and continue baking uncovered for another 15‑20 minutes until the top is bubbly and golden.

Pro Tip: If the top browns too quickly, loosely tent with foil.

Step 5: Rest, Garnish, Serve

Allow the casserole to rest for 10 minutes after removal; this helps the custard set. Sprinkle fresh chives over the top for color and a mild onion note, then slice and serve warm.

Pro Tip: Pair with a crisp orange juice or sparkling water.

Expert Tips

Tip #1: Use Day‑Old Bread

Stale bread absorbs the custard without turning mushy, giving the casserole a satisfying bite and preventing sogginess.

Tip #2: Cool the Sausage

Allow cooked sausage to cool slightly before mixing with bread; this prevents the custard from curdling and keeps the texture smooth.

Tip #3: Add a Crunchy Topping

Mix a handful of panko or crushed tortilla chips with melted butter and sprinkle before the final bake for extra crunch.

Frequently Asked Questions

Yes. Cool the baked casserole completely, slice, wrap each portion in foil, and freeze. Reheat in a 350°F oven for 20‑25 minutes or microwave individual pieces.

Swap cheddar for mozzarella, pepper jack, or a dairy‑free cheese blend. The flavor changes slightly, but the melt and richness remain.

Replace the bread cubes with equal‑volume cubed gluten‑free toast or roasted sweet potato dice. Ensure the sausage is certified gluten‑free.

Storage & Variations

Refrigerate leftovers in an airtight container for up to three days; reheat in the oven to retain crispness. For a lighter version, swap half the cheese for reduced‑fat mozzarella and use almond milk. Add spinach or kale for extra greens, or swap sausage for crumbled bacon for a smoky twist.
