Easy Sweet Potato Egg Casserole Recipe

Introduction

This Easy Sweet Potato Egg Casserole is a hearty and flavorful breakfast option that combines savory turkey sausage with tender sweet potatoes and a cheesy egg mixture. Perfect for a weekend brunch or feeding a crowd, it’s simple to prepare and packed with comforting 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 recommended)
• 10 large eggs
• 1/2 cup grated mozzarella cheese
• 1 tsp salt
• 1 tsp dried thyme
• 1/2 tsp pepper

Instructions

1. Step 1: Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish to prevent sticking. While the oven heats, chop all vegetables.
2. Step 2: Heat avocado oil in a large pan over medium heat. Add diced onion, green pepper, and sweet potatoes. Cook for 8-9 minutes, stirring occasionally, until vegetables soften. Add minced garlic for the last 1-2 minutes. Remove vegetables and spread evenly in the prepared casserole dish.
3. Step 3: Using the same pan, cook the turkey sausage until fully browned, breaking it into small pieces as it cooks. Add the cooked sausage to the vegetables in the casserole dish and stir to combine.
4. Step 4: In a mixing bowl, whisk together eggs, milk, grated mozzarella, salt, dried thyme, and pepper until smooth and well combined.
5. Step 5: Pour the egg mixture evenly over the vegetable and sausage base in the casserole dish. Stir gently to distribute. Bake in the preheated oven for 40-45 minutes, until the center is firm. If the top browns too quickly, loosely cover with foil.
6. Step 6: Remove from oven and let cool for 15 minutes before serving. This resting time allows the casserole to set and makes it easier to slice.

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 heats, 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. Add diced onion, green bell pepper, and sweet potatoes, cooking for 8-9 minutes until they begin to soften. Add minced garlic in the last 1-2 minutes and sauté briefly. Remove vegetables and spread evenly in the casserole dish.
3. Cook the Sausage: In the same pan, cook the turkey sausage thoroughly, breaking it into small pieces as it cooks. Once fully cooked, mix the sausage into the vegetables in the casserole dish.
4. Prepare the Egg Mixture: In a separate bowl, whisk together eggs, milk, grated mozzarella cheese, salt, dried thyme, and pepper until smooth and well combined.
5. Combine and Bake: Pour the egg mixture evenly over the sausage and vegetable mix in the casserole dish. Stir gently to distribute the eggs evenly. Bake in the preheated oven for 40-45 minutes until the center is firm. Cover loosely with foil halfway if the top browns too quickly.
6. Cool and Serve: Remove the casserole from the oven and let it cool for about 15 minutes before slicing and serving. This resting time allows the flavors to meld and makes serving easier.
