Key Ingredients & Substitutions

Breakfast Sausage: This ingredient adds a wonderful flavor to the casserole. You can substitute with turkey sausage or ground beef for a different taste. Vegetarian sausage is also a great option for a meat-free version.

Eggs: Large eggs are perfect for this recipe. If needed, you can use egg substitutes if you’re looking to cut cholesterol or are allergic to eggs. Just check the package instructions for equivalent quantities.

Milk: Whole milk gives a nice richness, but you can use 2% milk or even a non-dairy milk alternative like almond or oat milk for a lighter version.

Bread Cubes: Day-old bread works best as it absorbs the egg mixture well. If you don’t have any, you can use fresh bread, but toast it slightly first. Gluten-free bread is also a suitable substitute.

How Do I Ensure My Casserole is Cooked Evenly in the Crockpot?

Cooking time can vary depending on your crockpot, so it’s helpful to check it around the minimum cooking time. To ensure even cooking:

  • Use a crockpot liner or spray with nonstick cooking spray to prevent sticking.
  • Spread the mixture evenly in the crockpot without overpacking it.
  • Cover with a tight-fitting lid to keep the heat in during cooking.
  • For the best texture, avoid lifting the lid while it cooks, as this releases heat.

By checking a little early, you can prevent overcooking while ensuring all ingredients are set nicely. Enjoy your breakfast casserole worry-free!

Crockpot Breakfast Casserole

Ingredients You’ll Need:

  • 1 pound (450g) breakfast sausage (or ground sausage)
  • 6 large eggs
  • 1 cup whole milk
  • 4 cups bread cubes (day-old bread works best)
  • 1 cup shredded cheddar cheese, divided
  • 1/2 cup diced onion (optional)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon dried parsley (optional)
  • Fresh parsley, chopped for garnish

How Much Time Will You Need?

This delicious breakfast casserole takes about 15 minutes to prepare and then cooks in the crockpot for 6 to 8 hours on low or 3 to 4 hours on high. Perfect for an easy, grab-and-go breakfast!

Step-by-Step Instructions:

1. Cook the Sausage:

Start by heating a skillet over medium heat. Add the breakfast sausage and cook it until it’s browned and fully cooked. Use a spoon to break it apart as it cooks. If you’re adding onion, toss those in too, and cook until they are soft and translucent. Once done, drain any excess grease from the pan and set the mixture aside.

2. Prepare the Egg Mixture:

In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and dried parsley until everything is well combined and smooth.

3. Combined Ingredients:

Now, add the bread cubes, the cooked sausage mixture, and half of the shredded cheddar cheese to the egg mixture. Gently stir everything together, making sure the bread is nicely coated and all ingredients are evenly mixed.

4. Prepare the Crockpot:

Before pouring your mixture in, spray the inside of your crockpot with nonstick cooking spray. This will help prevent sticking and make cleanup easier!

5. Assemble in the Crockpot:

Pour the entire casserole mixture into the crockpot and spread it out evenly. Make sure it’s nice and flat so it cooks evenly.

6. Cooking Time:

Cover your crockpot with the lid. Cook on low for 6 to 8 hours or on high for 3 to 4 hours. You’ll know it’s ready when the eggs are set and the top has a slightly golden brown color.

7. Add the Cheese Topping:

About 15 minutes before you’re ready to eat, sprinkle the remaining shredded cheddar cheese over the top of the casserole. Re-cover and let it melt while waiting to serve!

8. Final Touches:

When cooking is complete, turn off the crockpot. For a tasty finishing touch, sprinkle some freshly chopped parsley on top to brighten it up.

9. Serve and Enjoy:

Carefully slice the casserole into portions using a spatula. Serve warm and enjoy your hearty breakfast with fresh fruit or your favorite morning sides!

This recipe is great for make-ahead breakfasts—perfect for busy mornings or a cozy brunch!

Can I Use Frozen Sausage for This Casserole?

Yes, you can! Just make sure to fully thaw the sausage in the fridge overnight before cooking it in the skillet. For quick thawing, you can also place it in a sealed plastic bag and submerge it in cold water until it’s soft enough to cook.

Can I Prepare This Casserole the Night Before?

Absolutely! You can assemble all the ingredients in the crockpot insert the night before and store it in the fridge. In the morning, just place the insert in the crockpot and set it to cook. Make sure to let it sit at room temperature for 30 minutes before starting if it’s cold from the fridge.

How Do I Store Leftovers?

Store any leftover casserole in an airtight container in the fridge for up to 3 days. To reheat, simply warm individual portions in the microwave or reheat the entire casserole in the oven at 350°F (175°C) until heated through.

Can I Customize the Ingredients?

Certainly! Feel free to substitute the sausage with turkey sausage, bacon, or even a meat alternative for a vegetarian option. You can also add in vegetables like bell peppers or spinach for extra nutrition and flavor!
