How to Make Spinach Brunch Casserole

Preheat oven to 375°F (190°C).
Grease a 13 x 9-inch baking pan.
In a large skillet, brown 1 lb Italian sausage and 4 oz cooked, chopped bacon, crumbling the sausage as it cooks.
Drain off any excess grease.
Add 1 medium onion (chopped), 8 oz mushrooms (sliced), and 2 cloves garlic (minced) to the skillet. Cook until onions are softened, about 5 minutes.
Spread the sausage and bacon mixture evenly in the prepared baking dish.
Sprinkle half of 1 (12 oz) jar roasted red peppers (drained) over the sausage mixture.
Top with 10 oz fresh spinach.
Sprinkle 1 cup shredded mozzarella cheese over the spinach.
In a large bowl, whisk together 1/4 cup all-purpose flour, 1/4 cup grated Parmesan cheese, 1 tsp seasoning salt, and 1 tsp dried basil.
In a separate bowl, whisk together 4 large eggs and 1 cup milk.
Gradually add the egg mixture to the flour mixture, whisking until smooth.
Pour the egg mixture evenly over the spinach in the baking dish.
Bake for 25-30 minutes, or until a knife inserted into the center comes out clean.
Remove from oven and sprinkle with the remaining roasted red peppers and 4 oz provolone cheese (shredded).
Return to oven for 2-3 minutes, or until the cheese is melted and bubbly.
Let stand for 5-6 minutes before cutting into squares and serving.
