An easy make-ahead breakfast casserole perfect for entertaining, serving groups, on holiday mornings, or for brunch. Packed with vegetables, this is always a favorite every time I serve it. Filled with favorite seasonal vegetables, high protein eggs, and a punch of savory bacon.
In a large bowl, whisk together eggs and milk; stir in garlic, basil, salt, pepper (1/2 tsp each). crushed red pepper flakes, shredded cheese and 1/4 cup Parmesan.
Spray the bottom of a 13 x 9 inch baking pan with cooking spray. Add the spinach, zucchini, cherry tomatoes, bell pepper, and bacon to the baking pan; spread evenly. Pour egg mixture on top, gently stirring mixture to distribute. Cover and refrigerate about 8 hours or overnight.
Preheat oven to 350 degrees.
Uncover the refrigerated casserole and sprinkle remaining 1/4 cup Parmesan cheese over the top. Bake 35 to 40 minutes or until just set and a knife inserted near center comes out clean. Let stand 10 minutes before serving. Sprinkle with fresh parsley.
This breakfast casserole can be assembled and baked the same day. Adjust the bake time to 30 to 35 minutes and check for doneness.
I like to use fresh baby spinach leaves, but if you substitute frozen spinach, be sure to thaw and squeeze out excess moisture.
