If heaven had a flavor, this would be it!
So, let’s get our aprons on and dive into the deliciousness!
Ingredients You’ll Need
Before we get cooking, make sure you have these ingredients on hand:
- 2 lbs of potatoes (any variety works, but russets are my favorite)
- 8 oz of mushrooms (button or cremini are perfect)
- 2 cups heavy cream (because, yes, we’re going all in on the creaminess!)
- 1 cup shredded cheese (cheddar, Gruyère, or whatever tickles your fancy)
- 2 tbsp butter
- 2 cloves garlic, minced
- Salt and pepper, to taste
- Fresh thyme (optional, but a little herb never hurts)
Let’s Get Cooking!
-
Preparation is Key! Start by preheating your oven to 375°F (190°C). Then, peel and slice the potatoes thinly (about 1/8-inch thick). A mandolin slicer can be a lifesaver here, just don’t lose a finger!
-
Sauté Those Shrooms! In a large skillet, melt the butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute. Toss in the sliced mushrooms, seasoning them with salt and pepper. Sauté until they’re golden and have released their moisture—about 5 to 7 minutes. The aroma will make you feel like a gourmet chef in no time!
-
Layering Time! Grab a greased baking dish and start layering. Place a layer of the sliced potatoes at the bottom, followed by half of the sautéed mushrooms. Sprinkle a bit of cheese on top (because, why not?). Repeat these layers until you run out of ingredients, finishing with a top layer of potatoes.
-
Cream it Up! Pour the heavy cream over the layered potatoes and mushrooms. It should cover everything. If you’re feeling fancy, toss a sprinkle of thyme on top for that chef’s touch.
-
Bake to Perfection! Cover the dish with aluminum foil and bake for 45 minutes. Then, remove the foil, sprinkle the remaining cheese on top, and bake for an additional 15 minutes until the cheese is bubbly and golden brown. Trust me, your kitchen will smell like heaven on a rainy day.
-
Let it Rest! Once out of the oven, let the gratin sit for about 10 minutes before digging in. This is the hardest part, but it’s necessary. (Need a distraction? I recommend a quick game of “What’s for dinner?” with the kids).
Cooking Tips for the Perfect Gratin
- If your sauce appears a little lumpy, don’t fret! That’s just the magic of cooking in action. It’ll still taste divine.
- For some added crunch, sprinkle breadcrumbs on top before the final baking step. Hello, crispiness!
- Experiment with other veggies like spinach or zucchini to shake things up a bit.

FAQs About Creamy Potato Mushroom Gratin
Can I substitute heavy cream in this recipe?
Absolutely! If you’re looking to lighten it up, half-and-half or a dairy-free milk can work, but the creaminess might take a hit. A foodie always finds a way!
How can I store leftovers?
Leftovers (if there are any!) can be stored in an airtight container in the fridge for up to 3 days. Reheat in the oven for the best texture. Microwaving is fine too; just be prepared for a less crispy top!
Can I use different cheeses?
Definitely! Get creative—fontina, mozzarella, or even a mix of your favorites can add a fun twist to the flavor profile!
