Tips for the Best Easy Veggie Omelet Casserole

✅ Use Fresh Ingredients – Fresh vegetables add the best flavor and texture. If using frozen veggies, thaw and drain excess moisture.

✅ Pre-Cook Certain Veggies – Sauté onions, bell peppers, and broccoli for a softer texture and richer taste. Tomatoes can be added raw for a fresh burst of flavor.

✅ Customize to Your Taste – Add mushrooms, spinach, zucchini, or any veggies you love. You can also mix in cooked meats like turkey, ham, or bacon for extra protein.

✅ Cheese Choices Matter – Cheddar adds a sharp taste, mozzarella gives a mild creaminess, and feta adds a tangy touch. Mix and match for different flavors!

✅ Avoid a Watery Casserole – If using watery veggies like tomatoes or zucchini, lightly salt and drain them first to remove excess moisture.

✅ Make It Ahead – Prepare the casserole the night before and bake it in the morning for a quick, hot breakfast.

✅ Storage & Reheating – Store leftovers in the fridge for up to 4 days. Reheat in the microwave or oven at 350°F (175°C) until warm.
