Ingredients

Here’s what you’ll need to create this comforting Bubble Up Breakfast Casserole:

  • 6 slices bacon, cut into bite-sized pieces
  • 1 pound breakfast sausage
  • 1 (16 ounce) can Grands biscuits (refrigerated, 8 count)
  • 8 large eggs
  • 1 ¼ cup milk
  • ½ teaspoon garlic powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 2 cups shredded cheese (cheddar, Colby Jack, or a blend)
  • Green onions, chopped (for garnish)

Swaps and Notes

  • Bacon & Breakfast Sausage: This combination provides a fantastic depth of flavor. You can use all bacon, all sausage, or even diced ham or a plant-based breakfast meat.
  • Grands Biscuits: The large, flaky layers of Grands biscuits work best for the “bubble up” effect. Other refrigerated biscuit brands might also work, but check the size and type.
  • Eggs: Large eggs are standard. For extra fluffiness, you can add a tiny pinch of baking powder to the egg mixture, or a bit of heavy cream instead of milk.
  • Milk: Any kind of milk (whole, 2%, or skim) will work.
  • Shredded Cheese: Cheddar cheese is classic for breakfast casseroles, but Colby Jack, Monterey Jack, a Mexican blend, or even a mix of cheeses would be delicious.
  • Seasoning: Adjust salt and pepper to taste. A pinch of onion powder in the egg mixture would also be a nice addition.
  • Green Onions: Chopped green onions add a fresh, mild onion flavor and vibrant color for garnish.

Instructions

Let’s get this delicious and easy Bubble Up Breakfast Casserole baking!

  1. Preheat Oven: Preheat your oven to 350°F (175°C).
  2. Cook Bacon: Heat a large 12-inch skillet (oven-safe, or transfer to a 9×13 baking dish later) over medium-high heat. Add the chopped bacon and cook until it’s crispy. Remove the cooked bacon with a slotted spoon and transfer it to a paper towel-lined plate to drain any excess grease.
  3. Cook Sausage: Add the breakfast sausage to the same skillet (using the rendered bacon fat for flavor!). Cook until it’s browned and crumbly, using a spoon to break it apart. Once cooked, remove the sausage from the skillet and transfer it to a plate.
  4. Prepare Baking Dish: Turn off the heat under the skillet. If your skillet is oven-safe, you can proceed to the next step using the same skillet. Otherwise, wipe out any remaining grease from the skillet and generously spray a 9×13-inch baking dish with cooking spray.
  5. Prep Biscuits: Open the can of Grands biscuits. Cut each biscuit into quarters. Place the cut biscuit pieces evenly into the bottom of your skillet or prepared 9×13 baking dish.
  6. Whisk Egg Mixture: In a medium bowl, add the 8 large eggs, 1 ¼ cup milk, ½ teaspoon garlic powder, ½ teaspoon salt, and ¼ teaspoon black pepper. Whisk until all ingredients are well combined and the eggs are frothy.
  7. Assemble Casserole: Sprinkle the cooked breakfast sausage evenly over the biscuit pieces in the skillet/baking dish. Add the cooked, drained bacon bits on top of the sausage (or sprinkle over the very top before baking for maximum crispiness). Pour the whisked egg mixture evenly over the sausage and biscuits. Finally, sprinkle 2 cups of shredded cheese over the top of the egg mixture.
  8. Bake: Place the casserole into the preheated oven. Bake for 30-35 minutes, or until the eggs are set in the center and the biscuits are golden brown and “bubbled up.” A toothpick inserted into the center should come out clean.
  9. Garnish & Serve: Remove the casserole from the oven and let it cool for 5 minutes before serving. This allows the casserole to set slightly. Garnish generously with minced green onions before serving. Enjoy your delicious and easy Bubble Up Breakfast Casserole!

Tips for Success

  • Don’t Overcook Sausage/Bacon: Cook just until done. They will continue to cook slightly in the oven.
  • Even Biscuit Distribution: Spreading the biscuit pieces evenly ensures every serving gets some of that fluffy biscuit goodness.
  • Slightly Underdone Eggs: If making ahead and freezing, you might undercook the eggs by a minute or two, as they will cook further when reheated.
  • Pat Dry Bacon: Ensure bacon is very crispy and well-drained to avoid a greasy casserole.
  • Use a Large Pan: A 12-inch oven-safe skillet or a 9×13 baking dish provides enough space for the biscuits to bubble up without overflowing.

Serving Suggestions and Pairings

This Bubble Up Breakfast Casserole is a complete meal on its own, but it pairs wonderfully with a few simple additions:

  • Fresh Fruit Salad: A light, refreshing fruit salad provides a nice contrast to the richness of the casserole.
  • Hot Sauce: Offer a variety of hot sauces for those who like a spicy kick.
  • Salsa or Ketchup: Classic condiments for a breakfast casserole.
  • Coffee or Juice: Essential beverages for a hearty breakfast.
