Cheesy Mushroom Scalloped Potatoes
This recipe combines tender potatoes, earthy mushrooms, and a creamy cheese sauce for a side dish that’s both comforting and flavorful.
Ingredients:
- 2 tablespoons butter
- 1 medium onion, diced
- 8 ounces sliced mushrooms
- 4 cloves garlic, minced
- 4 medium russet potatoes, thinly sliced (about 4 cups)
- 1/2 teaspoon dried thyme
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 1 (10.5 ounce) can condensed cream of mushroom soup
- 1 cup chicken broth
- 1 1/2 cups shredded cheddar cheese, divided
- 1/2 cup grated Parmesan cheese
Cooking Guide:
- Preheat oven to 375°F (190°C). Grease a 9×13 inch baking dish.
- In a large skillet over medium heat, melt butter. Add onion and cook until softened, about 5 minutes. Stir in mushrooms and cook until golden brown, about 5 more minutes. Add garlic and cook for 30 seconds, until fragrant.
- In a large bowl, combine potatoes, thyme, salt, and pepper. Pour in the cooked mushroom mixture and toss to coat.
- In a separate bowl, whisk together cream of mushroom soup and chicken broth. Pour the mixture over the potatoes and mushrooms, stirring gently to distribute evenly.
- Transfer the potato mixture to the prepared baking dish. Sprinkle with 1 cup of cheddar cheese.
- Bake uncovered for 45 minutes, or until potatoes are tender and a fork easily pierces through them.
- Remove from the oven and increase the temperature to 400°F (205°C). Sprinkle the remaining cheddar cheese and Parmesan cheese over the top.
- Bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
- Let cool slightly before serving.
Tips:
- For extra crispy edges, broil the casserole for a few minutes at the end, watching closely to avoid burning.
- To make this dish vegetarian, use vegetable broth instead of chicken broth.
- You can add other vegetables to this recipe, such as chopped carrots, peas, or broccoli. Simply cook them with the mushrooms and onion.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
- For a richer flavor, use a combination of Gruyere and Fontina cheese instead of cheddar.
- If your potatoes are very starchy, you may want to parboil them (boil them for a few minutes) before layering them in the baking dish. This will help to prevent them from becoming mushy.
