Recipe Overview

Prep Time: 20 minutes
Cook Time: 30 minutes
Total Time: 50 minutes
Servings: 8
Dietary Type: Vegetarian

Ingredients

1/4 cup margarine
8 ounces frozen mixed vegetables (corn, diced carrots, peas, & green beans)
1 (19 ounce) can cream-style corn
1 1/2 teaspoons baking powder
1/2 cup flour
3 eggs, beaten
1/2 cup milk
1 teaspoon salt
1 teaspoon garlic, minced
1/2 teaspoon black pepper (or to taste)
2 jalapenos, seeded & diced small
2 ounces drained pimientos (optional)
8 ounces muenster cheese, grated (reserve 2 oz)
1 tomato, very thinly sliced
Cooking spray

Equipment Needed

Rectangular glass casserole pan
Large glass mixing bowl
Microwave
Grater
Knife
Cutting board

Instructions

Preheat your oven to 350°F (175°C). Prepare a rectangular glass casserole pan by lightly coating it with cooking spray. This will prevent the casserole from sticking and make serving much easier.
In a large glass mixing bowl, combine the margarine and frozen mixed vegetables. Microwave for approximately 2 minutes, or until the vegetables are partially thawed and the margarine is melted. Keep a close eye on it to prevent splattering.
To the bowl with the vegetables and margarine, add the cream-style corn, baking powder, flour, beaten eggs, milk, salt, minced garlic, black pepper, diced jalapenos, and optional drained pimientos.
Stir all the ingredients together until thoroughly blended. Ensure there are no lumps of flour remaining, as this can affect the texture of the finished casserole.
Stir in 6 ounces of the grated muenster cheese into the mixture. Reserve the remaining 2 ounces for topping. Incorporating the cheese into the mixture ensures a creamy and cheesy interior.
Pour the combined mixture into the prepared casserole pan, spreading it evenly to ensure even cooking.
Arrange the very thinly sliced tomato on top of the casserole in a visually appealing pattern. The tomato adds a burst of freshness and color to the finished dish.
Sprinkle the reserved 2 ounces of grated muenster cheese evenly over the tomato slices. This will create a golden and bubbly topping.
Bake in the center rack of the preheated oven for 25-30 minutes, or until the casserole is set and the cheese is melted and lightly golden brown. The cooking time may vary depending on your oven, so check for doneness after 25 minutes. A toothpick inserted into the center should come out relatively clean.
Once baked, remove the casserole from the oven and let it set for about 5 minutes before cutting and serving. This allows the casserole to firm up slightly, making it easier to slice.

Expert Tips & Tricks

For a richer flavor, use melted butter instead of margarine.
If you’re sensitive to spice, omit the jalapenos or use a milder pepper, such as bell pepper.
To prevent the cheese from browning too quickly, tent the casserole with foil during the last 10 minutes of baking.
For a heartier casserole, add cooked sausage, bacon, or ham to the vegetable mixture.
Prepare the casserole ahead of time by assembling it and storing it in the refrigerator until ready to bake. Add a few minutes to the baking time if baking from cold.
If you find the casserole is getting too brown on top, you can lower the oven temperature slightly and continue baking until the center is set.
For even more flavor, consider adding a pinch of dried Italian herbs to the vegetable mixture.

Serving & Storage Suggestions

Serve the Colorful Corn & Veggie Casserole warm as a side dish or a vegetarian main course. It pairs well with roasted chicken, baked fish, or a simple green salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat in the microwave or oven until warmed through. For best results, add a splash of milk or cream to the casserole before reheating to prevent it from drying out.

The casserole can also be frozen for longer storage. Wrap tightly in plastic wrap and then in foil, or store in a freezer-safe container. It can be frozen for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
