Vegetable casserole

Since you asked for a vegetable casserole right after egg muffins, I’m going to give you the best of both worlds:

• Option 1: A Vegetable Egg Muffin Casserole (same great egg-bite flavor, but baked in one big dish—no muffin tin required).

• Option 2: A classic, hearty Vegetable Casserole (no eggs, perfect as a side dish or main vegetarian meal).

Just pick your vibe below!

Option 1: Vegetable Egg Muffin CASSEROLE (Bake in 1 dish)

(Think: a giant frittata—easier than individual muffins, zero sticking issues!)

Makes: 6–8 servings
Bake: 9×13-inch dish at 375°F (190°C) for 35–40 minutes.

Ingredients:

• 12 large eggs

• ½ cup milk

• 1 tsp salt + ½ tsp pepper

• 4 cups total mixed vegetables (choose 3–4 from below)

• 1 ½ cups shredded cheese (cheddar, mozzarella, or pepper jack)

Vegetable Mix-in Ideas (use 4 cups total):

• Sautéed mushrooms & onions

• Chopped spinach (fresh or frozen, thawed & squeezed dry)

• Diced bell peppers

• Broccoli florets (steam or roast for 5 mins first)

• Zucchini (sauté for 3 mins first to remove water)

• Cherry tomatoes (halved)

Instructions:

1. Preheat oven to 375°F. Grease a 9×13-inch baking dish.

2. If using any watery veggies (mushrooms, zucchini, onions), sauté them in a pan over medium heat for 5 minutes until softened. This prevents a soggy casserole.

3. Spread all your veggies evenly in the greased dish. Sprinkle cheese on top.

4. Whisk eggs, milk, salt, and pepper until frothy. Pour evenly over the veggies and cheese. Gently stir with a fork to distribute.

5. Bake for 35–40 minutes, until the center is puffed and a knife inserted comes out clean.

6. Let rest 10 minutes before slicing and serving.

Option 2: Classic Vegetable Casserole (No Eggs, Hearty Side Dish)

(Creamy, cheesy, and packed with veggies—perfect for holiday dinners or potlucks.)

Makes: 8–10 servings
Bake: 9×13-inch dish at 375°F for 30–35 minutes.

Ingredients:

• 6 cups mixed frozen or fresh vegetables (broccoli, cauliflower, carrots, peas, corn)

• 1 can (10.5 oz) cream of mushroom OR cream of celery soup

• ½ cup sour cream or plain Greek yogurt

• ½ cup mayonnaise

• 1 cup shredded cheddar cheese (divided in half)

• 1 cup crushed Ritz crackers or panko breadcrumbs

• 4 tbsp melted butter

• Instructions:

  1. Preheat oven to 375°F. Grease a 9×13-inch dish.

  2. If using fresh veggies, steam or boil them for 5–7 minutes until slightly tender. Drain well. If using frozen, thaw and drain thoroughly.

  3. In a large bowl, mix the soup, sour cream, mayo, and ½ cup of the shredded cheese. Fold in the drained vegetables until fully coated.

  4. Pour the mixture into the prepared dish and spread evenly.

  5. In a small bowl, mix the crushed crackers/panko with the melted butter and the remaining ½ cup of cheese. Sprinkle this over the top of the casserole.

  6. Bake for 30–35 minutes until hot and bubbly, and the topping is golden brown.

  3 “Make It Your Own” Twists

  Casserole Style	Swap These In
  Cheesy Broccoli-Rice	Add 2 cups cooked rice to Option 2, use broccoli & carrots only.
  Italian Veggie Bake	Add 1 tsp Italian seasoning + ½ cup marinara sauce to Option 2, top with mozzarella.
  Loaded Potato-Style	Use cauliflower instead of potatoes, add ½ cup cooked bacon bits (or smoked paprika for veggie version), and top with green onions.

  Quick Tip for Either: If you use watery vegetables (zucchini, mushrooms, tomatoes), always sauté or drain them first—this is the #1 secret to a non-soggy casserole!
