🥘 Ingredients

15 items

• 4 tablespoons Butter
• 1 medium, diced Yellow onion
• 3 minced Garlic cloves
• 2 cups, sliced Button mushrooms
• 2 cups, fresh or frozen Corn kernels
• 2 tablespoons All-purpose flour
• 1.5 cups Whole milk
• 0.5 cups Heavy cream
• 1.5 cups, shredded Cheddar cheese

• 0.5 teaspoon Black pepper

📝 Instructions

10 steps

1. Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set aside.

2. In a large skillet, melt the butter over medium heat. Add the diced onion and cook for 3-4 minutes, stirring occasionally, until softened.

3. Add the minced garlic and sliced mushrooms to the skillet. Cook for 5-6 minutes until the mushrooms release their moisture and begin to brown.

4. Stir in the corn kernels and cook for another 2-3 minutes. Sprinkle the flour over the mixture and stir well to coat the vegetables evenly.

5. Slowly pour in the milk and heavy cream while stirring constantly to prevent lumps. Cook for 3-4 minutes until the mixture thickens slightly.

6. Remove the skillet from heat and stir in the shredded cheddar cheese, grated Parmesan cheese, salt, and black pepper until well combined.

7. Transfer the mixture to the prepared baking dish, spreading it out evenly.

8. In a small bowl, toss the breadcrumbs with olive oil. Sprinkle the breadcrumb mixture over the top of the casserole.

9. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbly.

10. Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with chopped fresh parsley, if desired.
