I just made Twice Baked Stuffed Potatoes loaded with shiitake, creamy spinach and melting cheese and honestly they’re the kind of vegetarian dinner I’ll shamelessly brag about until you try them.

I’m obsessed with these Mushroom Potatoes Recipes because they somehow marry earthy shiitake mushrooms and gooey cream cheese into something wildly comforting. I love how the filling gets rich and melty, the kind of food that makes me cancel plans.

Best Recipes Vegetarian right here, no boring veg sides. And the potato skins get that crispy edge while the inside stays pillowy.

But it’s the mix of sharp cheese and spinach in every bite that makes me swoon. Totally mess-proof comfort food.

I crave it on a rainy night, or when I need a serious, satisfying dinner every single time.

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 400°F. Scrub the russets, poke them with a fork a few times, rub with 1 tablespoon olive oil and a little salt, then bake directly on the oven rack until tender, about 50 to 60 minutes depending on size. Let cool enough to handle.

2. While potatoes bake, heat 1 tablespoon olive oil and 2 tablespoons butter in a large skillet over medium heat. Add the sliced shiitake, chopped shallot, and a pinch of salt, cooking until mushrooms are brown and shallot is soft, about 6 to 8 minutes.

3. Add the minced garlic and thyme to the mushrooms, cook 30 seconds until fragrant, then stir in the spinach a handful at a time until it wilts. Squeeze in the lemon juice if using. Transfer the mushroom-spinach mix to a bowl and set aside.

4. Cut the baked potatoes in half lengthwise and scoop the flesh into a mixing bowl, leaving a thin shell so the skins hold their shape. Reserve the skins on the baking tray.

5. To the potato flesh add the cream cheese, sour cream, milk, 1 cup shredded cheddar, grated Parmesan, 1 teaspoon kosher salt, 1/2 teaspoon black pepper, and smoked paprika if using. Mash until mostly smooth but still a bit chunky. Taste and adjust seasoning.

6. Fold the mushroom-spinach mixture into the mashed potatoes, mixing gently so the filling stays fluffy and the mushrooms are evenly distributed.

7. Spoon the filling back into the potato shells, mounding it slightly. Sprinkle the remaining 1/2 cup cheddar over the tops.

8. Bake stuffed potatoes at 375°F until cheese is melted and tops are golden, about 15 to 20 minutes. If you want extra browning, switch to the broiler for 1 to 2 minutes but watch closely so it doesnt burn.

9. Remove, sprinkle with chopped parsley and an extra pinch of flaky salt if desired. Serve hot as a main or hearty side.

Equipment Needed

1. Oven (set to 400°F, then 375°F)
2. Baking sheet or rimmed tray (for the potato skins)
3. Large oven-safe skillet or frying pan (for mushrooms and spinach)
4. Mixing bowls (one large for scooping and one for the mushroom mix)
5. Potato masher or sturdy fork (for mashing the filling)
6. Chef knife and cutting board (for shallot, mushrooms, parsley)
7. Measuring cups and spoons
8. Spoon or rubber spatula (for folding and filling the shells)
9. Fork (to poke the potatoes)
10. Cheese grater or shredded cheese bag and a small spoon for sprinkling

FAQ

Q: Can I make these ahead of time?

A: Yes. You can bake the potatoes and make the mushroom-spinach filling a day ahead. Keep them separate in the fridge. Refill and reheat in a 375°F oven for 15 to 20 minutes until hot and cheese is melty.

Q: How do I get the potato skins crispy?

A: Rub the skins with olive oil and a pinch of salt before baking, and bake directly on the oven rack or on a baking sheet without covering. If they're a bit soft after stuffing, pop them under the broiler for 2 to 3 minutes to crisp the top, watching closely so they don't burn.

Q: My filling seemed watery. How do I avoid that?

A: Don't overcrowd the pan when cooking spinach so it steams instead of wilting dry. After cooking, press the spinach with a spoon or squeeze in a towel to remove excess liquid. Also let mushrooms brown well so they release less moisture into the filling.

Q: Can I swap the mushrooms or cheese?

A: Totally. Cremini or button mushrooms work fine. For cheese, Colby, Monterey Jack, or Gruyere are good swaps for cheddar. If you use a very salty cheese, cut back on added salt.

Q: Are these vegetarian and can they be veganized?

A: The recipe is vegetarian. To make it vegan, use vegan cream cheese, vegan sour cream, a plant milk, and dairy-free shredded cheese. Use olive oil in place of butter.

Q: What if I only have small potatoes or more than 4 people?

A: If your potatoes are smaller, use 2 to 3 per person depending on appetite. For more people, scale the filling ingredients up proportionally. You can also serve these as a side and stretch the recipe further.

Best Mushroom Stuffed Potatoes With Spinach & Cheese Recipe Substitutions and Variations

Russet potatoes: swap for Yukon Golds for a creamier, less fluffy mash, or use large baking sweet potatoes if you want a sweeter, earthier twist — still bake the same time.
Shiitake mushrooms: use cremini or baby bella mushrooms if shiitakes aren’t available, or chopped portobellos for a meatier bite. They cook the same, just watch moisture.
Cream cheese: replace with ricotta for a lighter, slightly grainy texture, or use Neufchâtel or full-fat Greek yogurt if you want tang and fewer calories.
Sharp cheddar: try Gruyère for a nuttier, melty option, or Monterey Jack for mildness and great meltability, even mozzarella works in a pinch.

Pro Tips

1. Roast potatoes a day ahead if you can. They mash better when they cool and dry out a bit, and it saves you time the day you serve them. Warm them gently before scooping so the skins dont crack.

2. Salt the mushroom pan early and high heat is your friend. Let the mushrooms get a real sear before stirring so you get deep browning and not just soggy mushrooms. If the pan looks dry, add a splash of the milk later rather than water.

3. Don’t overwhip the potato filling. Mash until mostly smooth but keep some texture so the stuffing holds up in the skins. Overworking makes them gluey. If too thick, add milk a tablespoon at a time; if too loose, stir in a little extra shredded cheddar.

4. For best flavor balance, taste and adjust twice: once after you mix the cream cheese, sour cream, and seasonings into the potatoes, and again after folding in the mushrooms and spinach. Acid like a squeeze of lemon or extra salt often makes the spinach pop, so be bold but taste as you go.
