Easy Sweet Potato Egg Casserole Recipe

Introduction

This Easy Sweet Potato Egg Casserole is a wholesome and flavorful breakfast dish that combines savory turkey sausage, sweet potatoes, and a cheesy egg mixture. Perfect for a weekend brunch or meal prep, it’s hearty and satisfying with simple ingredients.

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)
• 2 tbsp avocado oil (or olive oil)
• 1/2 cup milk (whole milk for richness)
• 10 large eggs
• 1/2 cup grated mozzarella cheese (Sargento brand recommended)
• 1 tsp salt
• 1 tsp dried thyme
• 1/2 tsp pepper

Instructions

1. Step 1: Preheat your oven to 350°F (175°C). Prepare your vegetables by chopping them finely. Grease a 9×13-inch casserole dish to prevent sticking.
2. Step 2: In a Dutch oven or large saucepan, heat avocado oil until hot. Add onion, green bell pepper, and sweet potatoes. Cook for 8-9 minutes, stirring occasionally, until vegetables soften. Add minced garlic in the last 1-2 minutes and sauté. Remove vegetables and spread evenly in the prepared casserole dish.
3. Step 3: Using the same pan, sauté the turkey sausage until fully cooked, breaking it into small pieces as it cooks. Combine the cooked sausage with the vegetables in the casserole dish.
4. Step 4: In a mixing bowl, whisk together eggs, milk, dried thyme, salt, pepper, and grated mozzarella until smooth.
5. Step 5: Pour the egg mixture evenly over the vegetable and sausage layer. Stir gently to distribute. Bake in the preheated oven for 40-45 minutes or until the center is firm. Cover with foil if the top browns too quickly.
6. Step 6: Remove from oven and let cool for about 15 minutes before serving to allow flavors to settle and make slicing easier. Enjoy!

Tips & Variations

• For extra flavor, add a pinch of smoked paprika or cayenne pepper to the egg mixture.
• Substitute turkey sausage with chicken sausage or vegetarian sausage to fit your dietary preference.
• Use sharp cheddar or pepper jack cheese instead of mozzarella for a different cheese profile.
• If you don’t have avocado oil, olive oil works perfectly as a substitute.

FAQs

Can I make this casserole ahead of time?

Yes, you can prepare the casserole the night before, cover it, and refrigerate it. When ready, bake it straight from the fridge, adding a few extra minutes to the baking time.

Can I use fresh thyme instead of dried thyme?

Absolutely. Use about 1 tablespoon of fresh thyme leaves in place of the 1 teaspoon of dried thyme for a fresher herb flavor.

Ingredients

Scale 1x2x3x

For the base:

• 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)
• 2 tbsp avocado oil (or olive oil)

For the egg mixture:

• 1/2 cup milk (whole milk for richness)
• 10 large eggs
• 1/2 cup grated mozzarella cheese (Sargento brand recommended)
• 1 tsp salt
• 1 tsp dried thyme
• 1/2 tsp pepper

Instructions

1. Preheat Oven and Prepare the Baking Dish: Preheat your oven to 350°F (175°C). While the oven is heating, chop all vegetables and grease a 9×13-inch casserole dish to prevent sticking during baking.
2. Cook the Vegetables: Heat avocado oil in a Dutch oven or large saucepan until hot. Add diced onion, green bell pepper, and cubed sweet potatoes. Cook for 8-9 minutes, stirring occasionally, until vegetables begin to soften. Add minced garlic in the last 1-2 minutes and sauté. Remove vegetables and spread evenly in the prepared casserole dish.
3. Cook the Sausage: In the same pan, add turkey sausage and sauté until fully cooked, breaking it into small pieces while cooking. Add cooked sausage to the vegetables in the casserole dish and combine well.
4. Prepare the Egg Mixture: In a separate bowl, whisk together eggs, whole milk, dried thyme, salt, pepper, and grated mozzarella cheese until smooth and fully combined.
5. Combine and Bake: Pour the egg mixture evenly over the sausage and vegetable mixture in the casserole dish. Stir gently to distribute the eggs throughout. Bake in the preheated oven for 40-45 minutes until the center is firm. If the top browns too quickly midway, cover loosely with foil to prevent burning.
6. Cool and Serve: Remove the baked casserole from the oven and let it cool for about 15 minutes before serving to allow flavors to meld and to make slicing easier. Serve warm and enjoy.

Notes

• Make sure the sweet potatoes are cut into uniform 1-inch cubes to ensure even cooking.
• If preferred, substitute turkey sausage with chicken sausage or a plant-based sausage for variation.
• Covering the casserole with foil halfway during baking prevents the top from burning while the inside cooks thoroughly.
• You can prepare the base mixture a day ahead and refrigerate to save time in the morning.
• Use whole milk for a richer texture; for a lighter version, use low-fat milk but expect a slightly less creamy result.
