Cutting board
Measuring cups and spoons

How to Make Baked Potatoes with Spinach and Mushrooms

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

In a large bowl, toss the potato wedges with 1 tablespoon olive oil, salt, and pepper. Spread them evenly on the baking sheet and roast for 30 to 35 minutes or until golden and crispy, flipping halfway through.

While the potatoes are baking, heat the remaining tablespoon of olive oil in a skillet over medium heat. Add the sliced mushrooms and cook for 5 to 7 minutes until browned.

Stir in the diced onion and garlic. Cook until translucent, about 2 to 3 minutes.

Add the spinach to the pan and cook until wilted, about 2 minutes. Season with a bit more salt and pepper.

Push the veggies to one side of the skillet. Add the vegan butter to the empty space, and once melted, whisk in the flour to create a roux. Slowly add the vegetable broth and plant-based milk, stirring constantly until smooth.

Let the mixture simmer for 4 to 5 minutes, allowing it to thicken. Stir in nutritional yeast if using, and adjust seasoning to taste.

Plate the roasted potatoes and spoon the creamy mushroom spinach mixture on top. Garnish with fresh herbs.

Roast potatoes on a single layer with space in between to ensure crispiness.
Season each layer – potatoes, mushrooms, and gravy – to build flavor.
For a protein boost, try topping with Crispy Cottage Cheese Chips.
Don’t rush the roux—it’s what makes the sauce rich and creamy.

Variations and Substitutions

Looking to customize your mushroom stuffed potatoes baking style?

Add protein by stirring in canned chickpeas or lentils with the mushrooms.
Sprinkle shredded dairy-free cheese before serving for extra indulgence.
Swap spinach for kale, Swiss chard, or even arugula for peppery flavor.

Common Mistakes to Avoid

Overcrowding the baking sheet leads to steaming instead of roasting.
Not drying the mushrooms before sautéing can result in a soggy texture.
Skipping the roux step will make the sauce runny and less flavorful.
Undercooking the potatoes results in a lack of crispness and structure.
Overseasoning the spinach-mushroom mix can overpower the natural flavors.

Serving and Presentation Ideas

Presentation makes a difference. Here’s how to make it look as good as it tastes:

Serve in a shallow bowl with the mushroom spinach mixture layered over the potatoes.
Garnish with a sprinkle of nutritional yeast, fresh parsley, or thyme leaves.
Drizzle with a bit of truffle oil for an upscale finish.
Serve alongside Mini Pumpkin Bread with Cinnamon Swirl for a warm autumn vibe.
Use as a main component in a vegetarian meal prep bowl with a grain like quinoa or wild rice.

This recipe is also great for batch cooking and bringing to potlucks or family-style dinners.

How to Store and Reheat Leftovers

Store leftovers in an airtight container in the refrigerator for up to 4 days.
To reheat, place in a skillet over medium heat with a splash of plant milk to rehydrate the sauce.
You can also microwave individual servings in 1-minute intervals, stirring between each.
Freeze only the spinach mushroom mixture (not the potatoes) for best texture on thawing.
