Step-by-Step Instructions(with Tips for Success)
1. Preheat Your Oven
Set your oven to 375°F (190°C). Position the rack right in the center for even baking. This is a crucial detail that ensures your casserole cooks uniformly, preventing soggy or overly browned edges.
2. Prepare the Baking Dish
Lightly brush a 9×13-inch baking dish with olive oil. Greasing is essential—it makes serving easy and adds a subtle flavor boost.
3. Sauté the Vegetables
Heat a large frying pan over medium-high and add olive oil. Toss in the shredded carrots and sliced mushrooms first; sauté for about 5 minutes until they soften and release their fragrances.
4. Wilt the Spinach
Add baby spinach to the pan and sauté another 5 minutes until it fully wilts and reduces in volume. Remove from heat and set aside.
5. Mix in Potatoes and Peppers
Stir roasted red pepper strips and frozen diced potatoes into the sautéed vegetables. Mix well to combine flavors evenly. (Don’t thaw potatoes—they help absorb moisture and keep the casserole set.)
6. Layer in the Baking Dish
Transfer the combined vegetable mixture to your greased baking dish. Spread it evenly across the bottom for a uniform bake.
7. Cheese Layer
Sprinkle shredded cheddar cheese evenly over the vegetables. This step ensures every slice has melty, cheesy goodness.
8. Make the Creamy Egg Mixture
In a large bowl, whisk together eggs, half-and-half, salt, and pepper until completely smooth. Pour this mixture evenly over cheese and vegetables. Ensure even distribution for a consistent texture.
9. Bake
Place the dish in the preheated oven and bake for 50 minutes. To test doneness, insert a toothpick or knife in the center; it should come out clean. If needed, extend baking time in 5-minute increments.
10. Cool and Serve
Let the casserole rest for at least 5 minutes before slicing. Resting helps the bake firm up for tidy portions.
