Description
A delicious and easy cheesy mushroom casserole made with Gruyere cheese, onions, and savory seasonings. This comforting dish is perfect as a side or a light main course.
Ingredients
Scale
- 1 tablespoon minced fresh garlic
- 32 oz sliced baby Bella or crimini mushrooms
- 1 cup shredded gruyere cheese
- 1/2 teaspoon dried thyme
- 1 cup chopped onions
- 1 teaspoon dried parsley for garnish
- 2 teaspoons Diamond Crystal kosher salt
- 1/2 teaspoon black pepper
- 1/4 cup olive oil, plus more for the pan
Instructions
- Preheat your oven to 400 degrees F. Grease a 2-quart baking dish with olive oil.
- Heat the olive oil in a large, deep skillet over medium-high heat. Add the mushrooms, the onion, and the kosher salt. Cook, stirring occasionally, until the mushrooms have released their liquid and the liquids have mostly evaporated, about 10 minutes.
- Add the garlic, black pepper and thyme. Cook, stirring, one more minute. Remove from heat.
- Transfer the mixture to the prepared baking dish. Sprinkle with the shredded cheese.
- Bake until hot and bubbly, about 15 minutes. Sprinkle with parsley and serve.
Notes
- Mushrooms are technically fungi, not vegetables.
- This casserole pairs well with steak or roast chicken.
- Consider serving with colored vegetables like steamed broccoli or a tomato salad.
- The recipe is naturally gluten-free and low-carb.
