Delightful Broiled Cremini and Mashed Potato Casserole

Ingredients

- 2 tablespoons olive oil
- 2 cups sliced cremini mushrooms
- 2 tablespoons tomato paste
- 1 can (15 oz) vegetable lentil soup
- 1 tablespoon low-sodium soy sauce
- 1 teaspoon Dijon mustard
- 3 cups refrigerated mashed potatoes
- 1/2 teaspoon freshly ground black pepper

Instructions

1. Preheat Broiler: Set your oven to broil on high. Allow it to preheat for about 10 minutes.

2. Sauté Mushrooms: In a large skillet over medium heat, warm 2 tablespoons of olive oil. Add the sliced cremini mushrooms and sauté for about 5 minutes, or until they become tender and begin to brown.

3. Prepare Base Mixture: Add 2 tablespoons of tomato paste to the mushrooms, stirring to combine. Cook for an additional 2 minutes to incorporate and deepen the flavors.

4. Add Soup and Seasonings: Pour in the can of vegetable lentil soup, 1 tablespoon of low-sodium soy sauce, and 1 teaspoon of Dijon mustard. Stir well to blend all ingredients. Cook for about 5 minutes, allowing the mixture to thicken slightly.

5. Assemble Casserole: Transfer the mushroom mixture into a broiler-safe casserole dish, spreading it evenly. Spoon 3 cups of refrigerated mashed potatoes over the top, smoothing with a spoon to create an even layer.

6. Season and Broil: Sprinkle a 1/2 teaspoon of freshly ground black pepper over the mashed potatoes. Place the dish under the broiler for 5-7 minutes, or until the top of the potatoes is golden brown and slightly crisp.

7. Rest and Serve: Remove the casserole from the oven and let it rest for a few minutes before serving. The resting time will enhance the flavors and make for cleaner slices when serving.
