Recipe Information
Ingredients
- 1 pound Whole30-compliant sausage
- 2 tablespoons olive oil
- 1 medium yellow onion, chopped
- 3 cloves garlic cloves, minced
- 1 large bell pepper, chopped
- 2 medium sweet potatoes, peeled and diced
- 1 medium zucchini, chopped
- 14.5 ounces canned diced tomatoes
- 1 teaspoon fresh thyme leaves
- 1 teaspoon fresh rosemary, chopped
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 2 cups spinach
Instructions
Preheat your oven to 375°F (190°C).
In a large skillet over medium heat, add 1 tablespoon of olive oil.
Add the sausage to the skillet and cook until browned, breaking it up with a spoon as it cooks, about 5-7 minutes.
Once the sausage is cooked, transfer it to a paper towel-lined plate to drain the excess fat.
In the same skillet, add the remaining tablespoon of olive oil.
Add the chopped onion and cook until softened, about 4 minutes.
Stir in the minced garlic and cook for an additional minute until fragrant.
Add the chopped bell pepper, sweet potatoes, and zucchini to the skillet, stirring to combine, and cook for about 5 minutes until they start to soften.
Pour in the canned diced tomatoes (with juices), and add the fresh thyme, rosemary, salt, and black pepper.
Stir to combine and let the mixture simmer for 5 minutes to develop flavors.
Return the cooked sausage to the skillet and mix well.
Fold in the spinach until it wilts slightly, about 1-2 minutes.
Transfer the sausage and vegetable mixture to a greased casserole dish, spreading it evenly.
Cover the casserole with foil and bake in the preheated oven for 30 minutes.
Remove the foil and bake for another 10-15 minutes, or until the sweet potatoes are tender.
Allow the casserole to cool for 5 minutes before serving. Enjoy!
