Step-by-Step Instructions
Follow these simple steps to create a breakfast that will have everyone asking for the recipe.
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) . Lightly coat a 9×13-inch baking dish with cooking spray to prevent sticking .
Step 2: Cook the Meats
In a large skillet over medium-high heat, add the breakfast sausage and chopped bacon. Cook, breaking the sausage apart with a wooden spoon, until the sausage is browned and the bacon is crisp . This takes about 8-12 minutes. Using a slotted spoon, transfer the cooked meat to a plate lined with paper towels to drain, leaving the flavorful drippings in the skillet .
Step 3: Sauté the Vegetables
Reduce the heat to medium. Add the diced onion and bell peppers to the skillet with the reserved drippings. Cook, stirring often, until the vegetables are tender and the onion is translucent, about 10 minutes . The drippings from the sausage and bacon add incredible flavor that oil alone can’t provide .
Step 4: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, milk (or half-and-half), Dijon mustard (if using), salt, and pepper until smooth and well combined .
Step 5: Combine Everything
Add the cooked meats, sautéed vegetables, frozen diced potatoes (unthawed), and drained black beans to the bowl with the egg mixture . Stir to combine thoroughly. Fold in about ¾ of the shredded cheese (saving the rest for the top). The cheese will bind the casserole together and add gooey goodness .
Step 6: Assemble and Bake
Pour the entire mixture into your prepared baking dish and spread it evenly. Sprinkle the remaining cheese on top . Bake for 45-50 minutes, or until the top is golden brown, the edges are set, and the center is no longer jiggly .
Step 7: Rest and Serve
Let the casserole stand for 10-15 minutes before slicing and serving. This allows the custard to set further, making it easier to cut clean pieces. Sprinkle with fresh chives before serving .
7 Essential Tips for the Best Cowboy Breakfast Casserole
Mastering this dish is easy with these expert tips:
- Don’t Skip the Meat Drippings: Cooking the vegetables in the rendered fat from the sausage and bacon is key to unlocking a deep, savory flavor that oil alone can’t replicate .
- Use Unthawed Frozen Potatoes: Using frozen diced potatoes straight from the bag prevents them from becoming mushy. They will cook perfectly in the oven’s heat .
- Prep the Night Before: This is a fantastic make-ahead meal. Assemble the entire casserole (up to the baking step), cover it with foil, and refrigerate overnight . In the morning, pop it straight in the oven. You may need to add 10-15 minutes to the baking time.
- Let It Rest: Allowing the casserole to rest after baking is crucial for a clean slice. The eggs need time to set so the casserole holds its shape .
- Customize Your Proteins: Use what you love. Swap the sausage for chorizo, the bacon for diced ham, or add leftover grilled chicken or steak .
- Don’t Overbake: The casserole is done when the center is set and no longer jiggly but is still soft and custardy. Overbaking can make it dry.
- Add a Crunchy Topping: For some extra texture, top the casserole with crispy tortilla strips or crumbled tortilla chips during the last 15-20 minutes of baking .
Delicious Variations to Explore
This recipe is a fantastic canvas for your culinary creativity. Here are a few ways to make it your own :
- Southwest Cowboy Casserole: Use chorizo instead of breakfast sausage. Add a can of diced green chiles to the vegetables and top with pepper Jack cheese.
- Loaded Cowboy Casserole: Swap the black beans for pinto beans, add some sautéed mushrooms, and top with crumbled tortilla chips.
- Potato Variations: Substitute frozen diced potatoes with Tater Tots, diced sweet potatoes, or shredded hash browns .
- Cheese Swaps: Use Monterey Jack, Colby, or even a spicy pepper jack for a different cheesy profile .
- Veggie-Packed: Add 5 ounces of fresh spinach to the skillet after sautéing the peppers and onions, stirring until wilted .
Storage and Reheating Guide
This casserole is perfect for meal prep and stores beautifully.
- Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 4 days .
- Freezing: Wrap cooled, individual portions tightly in foil, then transfer to a freezer-safe container. Freeze for up to 2 months .
- Reheating: Reheat individual portions in the microwave until warmed through. For best results, reheat in a 300°F (150°C) oven for 15-20 minutes to restore the crispy top .
