Ingredients
To make a scrumptious breakfast casserole, you will need the following ingredients:
- 3 garlic cloves (minced)
- 1 lb uncooked turkey sausage
- 5 cups cubed sweet potatoes (1-inch cubes)
- 1 green bell pepper (diced)
- 1/2 large yellow onion (finely diced)

How to Make Breakfast Casserole
Making a breakfast casserole is simple and enjoyable. Here’s how to do it step by step:
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures that your casserole cooks evenly.
- Prepare the Vegetables: Chop up your garlic, sweet potatoes, green bell pepper, and onion.
- Grease the Casserole Dish: Take a 9×13-inch casserole dish and grease it lightly to prevent sticking.
- Cook the Vegetables:
- In a Dutch oven, heat the avocado oil over medium heat.
- Add the chopped onion and green pepper, cooking them for about 8-9 minutes until they soften.
- Add minced garlic for the last couple of minutes to enhance the flavors.
- Combine Vegetables: Spread the cooked vegetables evenly in the greased casserole dish.
- Cook the Turkey Sausage: In the same pan, cook the turkey sausage until fully cooked. Then, mix it with the vegetables in the casserole dish.
- Prepare the Egg Mixture: In a large bowl, whisk together the eggs, milk, thyme, salt, pepper, and grated cheese.
- Combine it All: Pour the egg mixture over the sausage and vegetable mixture. Stir gently to combine everything.
- Bake: Place the casserole in the preheated oven and bake for about 40-45 minutes, or until the eggs are firm.
- Cool and Serve: Let it cool for 15 minutes before serving. This resting time helps the casserole set for easier cutting.
How to Serve Breakfast Casserole
Serving this breakfast casserole is easy. Cut it into squares and place them on plates. You can add toppings like salsa, avocado slices, or hot sauce for extra flavor. Pair it with fresh fruit or a light salad for a complete meal.
How to Store Breakfast Casserole
If you have leftovers, storing them is simple:
- In the Refrigerator: Place the casserole in an airtight container. It can be stored for up to 3-4 days.
- In the Freezer: Wrap it well in plastic wrap or aluminum foil and store it in a freezer-safe container. It can be frozen for up to 2-3 months.
To reheat, simply thaw it overnight in the fridge if frozen, then reheat in the oven or microwave until warm.
Tips to Make Breakfast Casserole
- Chop Ingredients Uniformly: This ensures everything cooks evenly.
- Use Leftover Vegetables: Feel free to add any leftover vegetables you have in your fridge to reduce waste.
- Experiment with Cheese: Try different cheese for unique flavor—cheddar or pepper jack work great, too.
Variations
There are plenty of ways to customize your breakfast casserole:
- Add Spinach or Kale: These greens add nutrition and flavor.
- Swap Sausage for Bacon: If you prefer, cooked bacon can give it a smoky taste.
- Make it Spicy: Add chopped jalapeños or sprinkle crushed red pepper for some heat.
FAQs
1. Can I prepare the casserole the night before?
Yes! You can assemble it and refrigerate it overnight. Just pop it in the oven in the morning.
2. Can I use different meats?
Absolutely! Feel free to use ground beef, ham, or even keep it vegetarian by omitting meat altogether.
3. How do I know when it’s done baking?
The casserole is done when it’s firm to the touch and the center no longer jiggles. A toothpick inserted should come out clean.
Making a breakfast casserole is not just about enjoying a meal; it’s about bringing warmth and comfort to your table. So gather your ingredients, invite your friends or family, and start making memories with this delightful dish!
