Save This hearty breakfast casserole combines day-old crusty bread cubes with shredded sharp cheddar and nutty Gruyère, soaked in a rich custard of eggs, whole milk, and heavy cream. Sweet roasted cherry tomatoes crown the top, adding bright flavor and beautiful color. The dish comes together quickly and can be assembled the night before, making it perfect for stress-free brunch entertaining or busy weekday mornings.
The smell of this strata baking takes me straight back to Christmas morning at my sister's house, when we'd all crowd into the kitchen in pajamas, coffee in hand, watching the oven window like hawks as the top turned golden and bubbled.
Last winter, I made this for a brunch with six friends and spent the entire morning just pouring mimosas and catching up instead of frantically cooking eggs while everyone wondered if they should help themselves to cereal.
Ingredients
- Day-old crusty bread cubes: Stale bread soaks up that custard like a dream without turning mushy or sad, so plan ahead or let your cubes sit out overnight
- Sharp cheddar and Gruyère: This combo gives you the sharp bite and that gorgeous, nutty, melt-in-your-mouth pull that makes strata feel like a special occasion
- Cherry tomatoes: When roasted, these little gems become concentrated bursts of sweetness that balance every rich, savory bite
- Eggs, milk, and cream: The holy trinity of breakfast custard that makes strata actual magic instead of just fancy bread pudding
- Onion and spinach: These sneak in some veggies while adding savory depth and pretty green flecks throughout the layers
Instructions
- Roast the tomatoes first:
- They need time to caramelize and concentrate while you prep everything else, so toss them on a sheet with olive oil and let them get jammy and sweet at 400°F for about 15 minutes.
- Soften your aromatics:
- Sauté the onion until it's translucent and sweet, then wilt the spinach into the pan so it releases any excess water that would otherwise make your strata soggy.
- Whisk up that luxurious custard:
- Beat your eggs with milk, cream, Dijon mustard, garlic powder, salt, and pepper until it's completely smooth and frothy.
- Build your masterpiece:
- Toss the bread cubes in the custard, fold in the sautéed veggies and both cheeses, then pour everything into your baking dish and tuck those roasted tomatoes across the top like little jewels.
- Bake into golden perfection:
- Cover it with foil for the first 30 minutes at 350°F, then uncover and let it get gorgeously browned and set for another 20 to 25 minutes.
Save This dish has become my go-to for those Sunday mornings when you want to feed people something that feels like a hug in food form.

Recipe FAQs
- → Can I make this strata ahead of time?
-
Yes, assemble the entire dish the night before, cover tightly, and refrigerate. In the morning, let it sit at room temperature for 30 minutes before baking as directed.
- → What type of bread works best?
-
Day-old crusty bread like sourdough, French bread, or artisan loaf works best. The slightly stale texture absorbs the custard without becoming mushy.
- → Can I substitute the cheeses?
-
Absolutely. Try mozzarella for mild creaminess, feta for tang, or pepper jack for spice. Any combination that melts well will work beautifully.
- → How do I know when the strata is done?
-
The strata is finished when the top is golden brown, the center is set (no liquid jiggles), and a knife inserted comes out clean.
- → Can I add meat to this dish?
-
Cooked bacon, ham, or sausage make excellent additions. Cook the meat first, then layer it with the vegetables and cheese before pouring over the egg mixture.
- → How long will leftovers keep?
-
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or oven until warmed through.
