Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Grease an 8×8-inch baking dish or a similar size with olive oil or cooking spray. This prevents sticking and ensures easy serving.

---

Step 2: Cook the Vegetables

In a medium skillet, heat 1 tablespoon of olive oil over medium heat. Add bell peppers, zucchini, and spinach, and sauté for 3–4 minutes until tender. If using tomatoes, stir them in at the end to maintain freshness. Remove from heat and let cool slightly.

Step 3: Whisk the Eggs

In a large bowl, whisk together eggs, milk, salt, pepper, and optional garlic or onion powder. Whisk gently until fully combined. Incorporating some air here helps make the casserole fluffy.

---

Step 4: Assemble the Casserole

1. Spread the sautéed vegetables evenly across the bottom of the greased baking dish.

2. Add any optional protein evenly over the vegetables.

3. Sprinkle ½ cup of shredded cheese across the top.

4. Pour the whisked egg mixture evenly over all ingredients.

5. Top with the remaining ½ cup of cheese for a lightly golden finish.

---

Step 5: Bake

Bake uncovered for 25–30 minutes, or until the eggs are fully set and the top is lightly golden. Check doneness by inserting a knife into the center—it should come out clean.

Let the casserole rest for 5 minutes before slicing to allow the layers to set and make serving easier.

Tips for a Perfect Lazy Weekend Casserole

• Use fresh or thawed vegetables: Avoid excess moisture that can make the casserole watery.

• Room-temperature eggs: These blend more smoothly and create a fluffier texture.

• Even layering: Helps ensure the casserole cooks uniformly.

• Avoid overbaking: Eggs continue cooking after removal, so slightly underbaking ensures a tender center.

• Garnish at the end: Fresh herbs brighten flavor and presentation.

---

Variations to Customize Your Weekend Breakfast

• Vegetarian: Skip protein or use beans, lentils, or tofu.

• Low-carb: Replace potatoes or heavier vegetables with cauliflower or zucchini.

• Dairy-free: Use plant-based milk and cheese alternatives.

• Mediterranean: Add olives, sun-dried tomatoes, and feta cheese.

• Herb-forward: Fresh dill, tarragon, or thyme can elevate flavor.

Make-Ahead and Storage Tips

Prepare Ahead

• Assemble the casserole the night before, cover with foil, and refrigerate. Bake in the morning for a quick, hot breakfast.

Store Leftovers

• Refrigerate cooled slices in an airtight container for up to 4 days.

• Freeze individual portions for up to 2 months. Thaw overnight before reheating.

Reheat

• Oven: Preheat to 350°F (175°C) and bake covered for 10–15 minutes.

• Microwave: Heat single slices for 1–2 minutes until warmed through.

Common Mistakes to Avoid

1. Excess water from vegetables: Sauté or drain before adding.

2. Overmixing eggs: Too much air can make eggs rubbery.

3. Skipping rest time: Helps the casserole firm up for easier slicing.

4. Overbaking: Leaves eggs dry. Slightly underdone center is ideal.

5. Uneven layering: Ensures all ingredients cook evenly.
