Step-by-Step Instructions
Preparation Steps
1. First, preheat your oven to 350°F (175°C). This step ensures even cooking for your casserole.
2. Next, grease a 9x13 inch baking dish. Use a little butter or cooking spray to prevent sticking.
3. In a large mixing bowl, whisk together the eggs and whole milk. Add the garlic powder, onion powder, salt, and black pepper. Mix until everything blends smoothly.
4. Now it's time to add the fun stuff! Stir in the grated cheddar cheese, chopped spinach, diced bell peppers, chopped onion, and halved cherry tomatoes. Each ingredient brings flavor and color.
5. Gently fold in the cubed bread. Make sure all the pieces get coated with the egg mix. This gives the casserole a nice texture.
6. Pour the mixture into the greased baking dish. Spread it out evenly for the best bake.
7. Bake your casserole in the preheated oven for 30-35 minutes. Look for a golden top, and check with a knife. If it comes out clean, it’s ready!
8. Once cooked, take it out and let it sit for about 5-10 minutes. This helps the layers set and makes slicing easier.
9. Before serving, garnish with fresh parsley. You can cut it into squares and arrange on a platter. For a twist, drizzle with hot sauce or add avocado slices on top. Enjoy!
Tips & Tricks
Cooking Tips
To get the best texture for your casserole, use fresh eggs. They help give it a light fluff. Whisk the eggs well with the milk to make them airy. This will keep the dish from being too dense.
If you want to swap ingredients, feel free! You can use any cheese you love. Try feta for a tangy twist or mozzarella for a milder flavor. You can also change the veggies. Zucchini, mushrooms, or kale work great here.
To enhance flavors, add herbs. Fresh basil or thyme can brighten the dish. A splash of hot sauce can add a fun kick. If you want a richer taste, use cream instead of milk. Just remember to adjust the seasoning for any changes.
Pro Tips
- Use Fresh Ingredients: Always opt for fresh vegetables to enhance the flavor and nutritional value of your casserole.
- Let It Rest: Allowing the casserole to sit for 5-10 minutes after baking helps it set, making it easier to slice and serve.
- Customize Your Veggies: Feel free to swap in your favorite vegetables or whatever you have on hand for a personalized touch.
- Store Leftovers Properly: Refrigerate any leftovers in an airtight container for up to 3 days, and reheat in the oven for best results.
Variations
Ingredient Swaps
You can easily change this dish to match your taste. Here are some fun swaps:
- Vegetable Combinations: Try using zucchini or mushrooms instead of spinach. You can also add broccoli or asparagus for more crunch. Carrots and corn can add a nice sweet touch. Mix and match to find your favorite mix!
- Cheese Alternatives: If you want a different flavor, use feta or mozzarella. Cream cheese can add a rich, creamy taste. For a spicy kick, try pepper jack cheese or a sharp blue cheese.
- Gluten-Free Bread Options: If you need a gluten-free dish, select gluten-free bread. You can also use corn tortillas or quinoa for a different texture. These options keep the casserole tasty and friendly for all diets.
Feel free to get creative! No matter what you choose, this casserole will still be a hit.
Storage Info
Storing Leftovers
To keep your cheesy veggie breakfast casserole fresh, start by letting it cool. After it cools, cover it tightly with plastic wrap or foil. You can also store it in an airtight container. Then, put it in the fridge. It stays good for up to four days.
If you want to save it longer, freezing is a great option. Cut the casserole into individual portions. Wrap each piece in plastic wrap, then in foil. Label and date each package. When stored this way, it can last for up to three months in the freezer.
When it's time to eat, reheating is key for keeping the flavor. For the best results, thaw the casserole in the fridge overnight before reheating. To warm it up, place the pieces in a baking dish. Cover with foil to prevent drying out. Heat in a preheated oven at 350°F (175°C) for about 15-20 minutes. You can also use the microwave, but check often to avoid overheating. Enjoy every bite!
