Wake up to a taste of Italy! Our Easy Cheesy Overnight Italian Strata recipe, loaded with pancetta, gruyere, and parmesan, turns your bread leftovers into a mouthwatering breakfast treat.

Here’s my latest obsession: Overnight Strata. I have been on such a leftover bread kick lately! It started with Greek Panzanella. Then, there was the Costa Rican Bread Pudding.
Now, it’s all about the Italian Strata recipe. This is just pure brilliance.

How to Make Italian Strata Recipe
Step #1: Heat a large, heavy skillet over medium heat and sauté pancetta until crisp. Remove and set aside. Add the olive oil to the pan and heat for 30 seconds. Add the onions and garlic, then sauté for five minutes. Turn off the heat and set aside.
Step #2: Spread one-third of the bread cubes in a well-buttered 3-quart baking dish. Top with one-third of the pancetta, one-third of the onion mixture, and one-third of each cheese. Repeat layering twice with the remaining bread, pancetta, onions, and cheese.
Step #3: Whisk together the eggs, milk, salt, pepper, and nutmeg. Pour evenly over the strata, then cover with plastic wrap and chill for at least 8 hours or up to one day.
Step #4: The next day, let it stand at room temperature while preheating the oven to 350°F (177°C). Bake uncovered for 45 to 55 minutes, or until golden brown and cooked through. Let stand for 5 minutes before serving.

Expert Tips
- Balanced Bread Moisture: Ensure your bread cubes are slightly stale; this helps them absorb the egg mixture without becoming too soggy.
- Even Cheese Distribution: Grate your Gruyère and Parmesan cheeses finely to ensure they melt evenly and enhance every bite with cheesy goodness.
- Skillet Size Matters: Use a skillet large enough to sauté the pancetta, onions, and garlic without overcrowding. This ensures even cooking and perfect crisping of the pancetta.

I like this strata and am going to make it this weekend. I don’t have the exact ingredients, so will use what I have. Its so similar to bread pudding except it is cheesy in a great way. Thanks Anetta.
