History and Origin
Breakfast casseroles, like the one we’re focusing on here, became popular in the mid-20th century in the United States, as home cooks sought easy, convenient meals for family gatherings and busy mornings. The concept of a “casserole” (from the French word for “pan” or “pot”) has been around for centuries, originating in European countries. Early casseroles were often savory dishes made by layering ingredients like meat, potatoes, and vegetables, then baking them in a pot or dish.
Breakfast casseroles, however, became a mainstream staple in the U.S. largely thanks to the rise of convenience cooking in the 1950s and 1960s. This era saw the invention of products like pre-packaged hashbrowns, frozen breakfast meats, and ready-to-use cheeses, all of which made preparing a breakfast casserole much simpler. These casseroles were often baked in a single pan, making cleanup easy, and could be made ahead of time to serve large groups, making them ideal for holiday breakfasts, brunches, and potlucks.
The One-Pan Cheesy Breakfast Casserole is an extension of this tradition, bringing together comfort food ingredients that are both filling and easy to prepare, while offering a modern twist by simplifying the process into a “one-pan” meal.
Ingredients
The ingredients for a One-Pan Cheesy Breakfast Casserole are simple and often pantry staples. Below is the basic list of ingredients, with options for customization.
Basic Ingredients:
- 8 large eggs – The foundation of the casserole, binding all the ingredients together and providing a rich, protein-packed base.
- 1 cup milk – Adds creaminess to the egg mixture. You can use whole milk, half-and-half, or even a dairy-free option like almond milk.
- 2 cups shredded cheese – A blend of cheddar, mozzarella, and/or Monterey Jack is a common choice, but feel free to experiment with your favorites (Gruyere, goat cheese, or even a spicy pepper jack).
- 1 tablespoon olive oil or butter – For sautéing vegetables and greasing the pan.
- 1 cup diced onion – Adds flavor and depth to the casserole.
- 1 bell pepper, diced – A colorful addition that pairs well with eggs and cheese.
- 2 cups frozen hashbrowns or cubed potatoes – These provide bulk and texture. Frozen hashbrowns are a convenient choice, but you can also use leftover cooked potatoes.
- 1 pound breakfast sausage (plant-based or regular) – The meat adds flavor and protein. Feel free to substitute with a vegetarian sausage or other protein of choice.
- 1 teaspoon garlic powder – For added seasoning.
- 1 teaspoon paprika – A subtle smoky flavor that enhances the overall taste.
- Salt and pepper – To taste.
Optional Ingredients for Customization:
- Fresh herbs like parsley, chives, or cilantro – For garnish and fresh flavor.
- Sour cream or hot sauce – For serving and adding an extra layer of richness or spice.
- Spinach or other leafy greens – For added vegetables and nutrients.
- Mushrooms, sliced – A great addition for umami and texture.
- Tomatoes – Adds freshness and color, particularly if you want to give the dish a more Mediterranean twist.
Instructions
This One-Pan Cheesy Breakfast Casserole is straightforward to prepare, and the best part is that it all comes together in one dish. Here’s how you can make it step by step.
Step 1: Preheat and Prep the Pan
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray. You can also use a large oven-safe skillet if you prefer to cook and serve the casserole in the same pan.
Step 2: Cook the Breakfast Sausage (or Plant-Based Sausage)
In a large skillet, cook the crumbled breakfast sausage (or plant-based sausage) over medium heat. Cook until browned and crispy, about 5-7 minutes. Once done, remove the sausage from the pan and set it aside. If there’s excess fat in the skillet, drain it off before continuing.
Step 3: Sauté the Vegetables
In the same skillet, add the diced onion and bell pepper. Sauté for about 5 minutes, or until softened. If you’re using other vegetables, like spinach or mushrooms, add them during this step and cook until they’re tender.
Step 4: Prepare the Egg Mixture
In a large bowl, whisk together the eggs, milk, garlic powder, paprika, salt, and pepper until fully combined and smooth. Stir in half of the shredded cheese to the egg mixture.
Step 5: Assemble the Casserole
Spread the frozen hashbrowns or cooked potatoes evenly in the bottom of the prepared baking dish or skillet. Then, layer the cooked sausage and sautéed vegetables on top. Pour the egg and cheese mixture over the top, ensuring everything is evenly distributed.
Step 6: Bake
Top the casserole with the remaining cheese and bake it in the preheated oven for 25-30 minutes, or until the eggs are set and the top is golden and bubbly. You can check for doneness by inserting a knife into the center—if it comes out clean, the casserole is ready.
Step 7: Garnish and Serve
Let the casserole cool for a few minutes before slicing and serving. Garnish with fresh herbs or a dollop of sour cream, if desired.
Pairing and Serving Suggestions
The One-Pan Cheesy Breakfast Casserole is a complete meal in itself, but there are a few side dishes that can complement the flavors:
- Fresh Fruit: A simple fruit salad with berries, melon, and citrus can provide a refreshing contrast to the richness of the casserole.
- Avocado Toast: A light and creamy side that pairs wonderfully with the cheesy casserole.
- Vegetarian Sausage or Grilled Tofu: For a protein-packed, savory addition to the meal.
- Hot Sauce: A few dashes of your favorite hot sauce or salsa can add some kick and freshness.
If you’re serving this casserole for brunch, consider pairing it with fresh coffee, fresh-squeezed orange juice, or even a mimosa for a more festive occasion.
Variations of the Recipe
While the classic One-Pan Cheesy Breakfast Casserole is delicious as is, there are plenty of ways to customize it to suit your tastes or dietary preferences.
1. Vegetarian Version:
Swap out the sausage for a plant-based protein like veggie sausage, tofu scramble, or more vegetables like zucchini, mushrooms, and spinach. You could also include beans like black beans or kidney beans for added protein.
2. Low-Carb/Keto Version:
Replace the hashbrowns with riced cauliflower or sliced zucchini to lower the carb count. You can also use full-fat cream instead of milk for a richer, keto-friendly dish.
3. Spicy Version:
For those who enjoy a bit of heat, consider adding diced jalapeños, spicy chorizo-style vegetarian sausage, or a dash of cayenne pepper to the egg mixture.
4. Mexican-Inspired:
Transform this casserole into a Mexican-inspired dish by adding ingredients like black beans, corn, diced tomatoes, and chili powder. Top with some fresh cilantro, avocado, and a drizzle of sour cream for extra flavor.
5. Brunch Version:
Add more brunch elements, such as cooked vegetarian sausage, crumbled croissants, or English muffins to make the casserole more indulgent.
