Cooking Instructions for Roasted Veggie Breakfast Casserole

Let’s dive into the cooking process of the Roasted Veggie Breakfast Casserole. The steps are simple, allowing you to enjoy a delicious breakfast in no time. Follow these easy instructions to create a hearty and flavorful dish that will impress.
- Preheat your oven to 425˚F. This initial step is crucial as it will help to roast the vegetables perfectly, bringing out their natural sweetness and flavors.
- Toss the cubed sweet potato, diced red pepper, onion, and chopped mushrooms in a mixing bowl with the olive oil and 1/2 teaspoon salt. Ensure that all the vegetables are evenly coated with oil.
- Spread the seasoned vegetables on a baking sheet in a single layer. Roast them in the oven for 14 to 18 minutes, or until the sweet potato is tender and slightly golden, which enhances the flavors.
- While the vegetables roast, whisk together the eggs, half and half, remaining salt, pepper, and thyme in a large bowl. Make sure the mixture is well combined and fluffy.
- Once the vegetables are ready, remove them from the oven and let them cool slightly. Transfer the roasted veggies to a 13×9 inch baking dish, spreading them evenly across the bottom.
- Add in the chopped spinach and sprinkle the goat cheese crumbles over the vegetables. The cheese will melt beautifully, adding a delicious creaminess to the dish.
- Pour the egg mixture evenly over the vegetable and cheese layer. Gently shake the dish to help the egg mixture distribute evenly throughout.
- Place the dish back in the oven and bake for 30 to 40 minutes, or until the center of the casserole is cooked through and set, with a golden top.
- Once done, remove the casserole from the oven and let it cool for a few minutes before slicing. Cut it into 12 to 15 slices for serving.
- Serve warm and enjoy the comforting flavors of your Roasted Veggie Breakfast Casserole with friends and family!
