Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 tablespoon olive oil
1 pound ground beef
1 small onion, diced
3 cloves garlic, minced
8 ounces mushrooms, sliced
1/2 cup dried brown or green lentils
1 1/2 cups beef broth
1 tablespoon tomato paste
1 teaspoon dried thyme
1/2 teaspoon dried rosemary
1 teaspoon salt
1/2 teaspoon black pepper
3–4 medium potatoes, thinly sliced
1/2 cup shredded cheddar cheese (optional)
Fresh parsley, chopped (optional, for garnish)

directions

I start by preheating the oven to 375°F (190°C).

In a large skillet, I heat the olive oil over medium heat. I add the diced onion and cook until softened, about 4–5 minutes. I stir in the garlic and cook for another 30 seconds.

I add the ground beef and cook until browned, breaking it up as it cooks. If necessary, I drain any excess grease. I stir in the sliced mushrooms and cook until they release their moisture and begin to brown.

I rinse the lentils and add them to the skillet along with the beef broth, tomato paste, thyme, rosemary, salt, and black pepper. I bring the mixture to a gentle simmer and let it cook for about 15 minutes, allowing the lentils to begin softening and the mixture to thicken slightly.

I transfer the beef and lentil mixture into a greased baking dish and spread it evenly. I arrange the thinly sliced potatoes in overlapping layers on top. I lightly season the potatoes with a small pinch of salt and brush them with a little olive oil.

I cover the dish with foil and bake for 30 minutes. Then I remove the foil and bake for another 20–25 minutes, until the potatoes are tender and golden on top. If I am using cheese, I sprinkle it over the potatoes during the last 10 minutes of baking so it melts and becomes bubbly.

I let the hotpot rest for about 10 minutes before serving and garnish with fresh parsley if I like.

Servings and timing

This recipe makes about 4–6 servings.

Prep time: 20 minutes
Cook time: 1 hour
Total time: 1 hour 20 minutes

Variations

I sometimes add diced carrots or celery to the beef mixture for extra vegetables. When I want a richer flavor, I stir in a splash of Worcestershire sauce. I also like swapping cheddar for Gruyère for a more savory topping. For a lighter version, I use ground turkey instead of beef.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 4 days. I reheat portions in the oven at 350°F (175°C) until warmed through, or in the microwave in short intervals. I can also freeze the fully baked hotpot for up to 2 months. I thaw it overnight in the refrigerator before reheating.

FAQs

Can I use canned lentils instead of dried?

I can use canned lentils to save time. I drain and rinse them well and reduce the simmering time since they are already cooked.

What type of potatoes work best?

I prefer Yukon Gold or russet potatoes because they become tender and slightly crisp on top.

Do I need to cook the lentils fully before baking?

I partially cook the lentils on the stovetop so they finish cooking perfectly in the oven.

Can I prepare this ahead of time?

I assemble the hotpot a day in advance, cover it, and refrigerate it. I bake it when ready to serve, adding a few extra minutes if needed.

How do I know when it is fully cooked?

I check that the potatoes are fork-tender and that the filling is bubbling around the edges.

Conclusion

I enjoy making this mushroom, ground beef, and lentil potato hotpot because it delivers warmth and comfort in every bite. I love the combination of savory meat, hearty lentils, earthy mushrooms, and tender baked potatoes. It is a dependable, satisfying dish that I turn to whenever I want a wholesome and filling meal.
