How To Make Martha Stewart Easter Breakfast Casserole
Preparing the Sausage and Vegetables
Start by heating olive oil in a large skillet over medium-high heat. Brown the sausage, breaking it apart as it cooks, until it’s beautifully golden and fragrant. Remove the cooked sausage and set it aside, but keep those delicious drippings in the skillet. Sauté the onion and sliced mushrooms for about 5-7 minutes until soft. Then, add the spinach and cook until wilted, filling your kitchen with a wonderful aroma.
Assembling the Casserole
Grease a 9×13-inch baking dish to prevent sticking. Layer half of the bread cubes at the bottom, followed by half of the sausage mixture, half of the sautéed vegetables, and half of the shredded Gruyère cheese. Repeat this layering process with the remaining ingredients for a hearty, flavorful casserole.
Making the Egg Custard
In a large bowl, whisk together the eggs, milk, heavy cream, Dijon mustard, nutmeg, salt, and pepper until everything is combined smoothly. Pour this custard mixture evenly over the layered ingredients in the baking dish. Gently press down on the bread to help it absorb the custard, creating that luscious, creamy texture.
Baking the Casserole
Cover the baking dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight. When you’re ready to bake, preheat your oven to 350°F (175°C). Allow the casserole to sit at room temperature for 30 minutes before placing it in the oven. Bake uncovered for 50-60 minutes until it’s puffed, golden brown, and the center is set. Let it rest for 10 minutes before slicing and serving for the best experience.
Recipe Tips
Best Bread Choices
Using slightly stale or dry bread enhances the custard absorption, making each bite delightful. If your bread is fresh, a light toast will work wonders too.
Enhancing Flavor with Overnight Chilling
Refrigerating the casserole overnight allows the flavors to meld beautifully, resulting in a richer taste and better texture. It’s worth the wait!
Baking Tips for Perfect Texture
Be careful not to overbake your casserole. It should be set in the center, with a knife coming out clean when inserted. This will ensure the perfect creamy bite.
