How to Make healthy meal prep sweet potato and winter vegetable casserole
Preheat your oven to 400°F (200°C). This will ensure that your casserole cooks evenly and at the right temperature.
Peel and dice the sweet potatoes into 1-inch cubes. Place them in a large bowl and toss with 2 tablespoons of olive oil, salt, and pepper until they're evenly coated.
Spread the sweet potatoes out in a single layer on a baking sheet lined with parchment paper. Roast in the preheated oven for 20-25 minutes, or until they're tender and lightly browned.
Trim and halve the Brussels sprouts, and peel and slice the carrots. Chop the onions and mince the garlic. Place the vegetables in a large bowl and toss with 1 tablespoon of olive oil, salt, and pepper until they're evenly coated.
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the chopped onions and cook until they're translucent, about 5 minutes. Add the minced garlic and cook for an additional minute. Add the Brussels sprouts and carrots, and cook until they're tender, about 10-12 minutes.
In a large bowl, combine the roasted sweet potatoes, sautéed winter vegetables, and chopped fresh herbs. Season with salt and pepper to taste.
Transfer the casserole mixture to a 9x13 inch baking dish. Bake in the preheated oven for 25-30 minutes, or until the casserole is hot and the flavors have melded together.
Remove the casserole from the oven and let it cool for a few minutes. Serve hot, garnished with additional fresh herbs if desired.
Tips for Perfect Results
Look for sweet potatoes that are firm and free of bruises. This will ensure that they're sweet and flavorful.
Cook the winter vegetables until they're tender, but still crisp. This will help preserve their flavor and texture.
Fresh herbs add a bright, fresh flavor to the casserole. Choose herbs that complement the sweet potatoes and winter vegetables, such as parsley, rosemary, or thyme.
Let the casserole rest for a few minutes before serving. This will allow the flavors to meld together and the casserole to set.
Feel free to experiment with different spices and seasonings to add more flavor to the casserole. Some options include paprika, cumin, or smoked paprika.
This casserole is perfect for meal prep. Simply assemble the casserole, cover it with plastic wrap or aluminum foil, and refrigerate or freeze until ready to bake.
