Best Mushroom Thanksgiving Recipes – Savory Side Dish

As a food blogger, I've tested dozens of Thanksgiving sides, but this mushroom medley always steals the show. It's the dish that disappears first from the table, even with turkey and all the trimmings around. The earthy depth of the mushrooms, combined with a velvety sauce, makes it feel both indulgent and homey.

I remember the first Thanksgiving I made this for my family. My brother, who claimed he hated mushrooms, went back for seconds and asked for the recipe. That's when I knew it was a keeper. It's now a non-negotiable part of our holiday spread, and I'm so excited to share it with you.

This recipe is designed to be forgiving: you can prep the mushrooms ahead, use any mix you like, and it still turns out perfect. It's the kind of side dish that makes you look like a rockstar in the kitchen without hours of fuss.

About the Ingredients

2 lbs (900g) mixed mushrooms (cremini, shiitake, oyster), sliced

Cremini and shiitake add depth, oyster mushrooms bring a delicate texture. Feel free to swap in portobello or button mushrooms; just adjust cooking time.

4 tablespoons (56g) unsalted butter, divided

Use salted butter if that's what you have, but reduce added salt later. Vegan? Use olive oil or a plant-based butter.

1 medium yellow onion, finely chopped

Shallots work beautifully too—use 2 shallots for a milder flavor.

4 cloves garlic, minced

Fresh garlic is best, but 1 teaspoon garlic powder can substitute in a pinch.

2 tablespoons all-purpose flour

This thickens the sauce. For a gluten-free version, use cornstarch (mix with 2 tbsp cold water).

1 cup (240ml) low-sodium chicken or vegetable broth

Vegetable broth keeps it vegetarian. Low-sodium lets you control the salt.

1 cup (240ml) heavy cream

For a lighter option, use half-and-half or a can of coconut milk for a dairy-free twist.

1 teaspoon fresh thyme leaves (or 1/2 tsp dried)

Thyme pairs perfectly with mushrooms. Rosemary or sage also work.

1/2 cup (50g) grated Parmesan cheese

Parmesan adds umami. Use a vegetarian-friendly alternative or nutritional yeast if needed.

Salt and freshly ground black pepper, to taste

A good pinch of salt brings out the mushroom's natural flavor.

Tips & Tricks

Don't crowd the pan

Sauté mushrooms in batches so they brown instead of steam.

• Slice mushrooms uniformly so they cook evenly.
• For extra flavor, deglaze the pan with a splash of white wine or sherry before adding broth.

Step-by-Step Instructions

1. Sauté the mushrooms

In a large skillet over medium-high heat (350°F/175°C), melt 2 tablespoons butter. Add mushrooms in a single layer and cook without stirring for 4-5 minutes until golden brown on one side. Stir and continue cooking for 3-4 minutes until tender. Transfer to a plate.

2. Cook the aromatics

In the same skillet, melt remaining butter over medium heat (325°F/160°C). Add onion and cook for 3-4 minutes until translucent. Add garlic and cook for 1 minute until fragrant.

3. Make the roux

Sprinkle flour over the onion mixture and stir constantly for 1-2 minutes until the flour is fully incorporated and lightly golden.

4. Add liquids gradually

Slowly pour in the broth while whisking to prevent lumps. Then add the cream and thyme. Bring to a simmer and cook for 2-3 minutes until the sauce thickens slightly.

5. Combine and season

Return the mushrooms to the skillet. Stir in the Parmesan cheese and season with salt and pepper. Cook for 2-3 minutes until everything is heated through and the sauce is creamy.

6. Serve and garnish

Transfer to a serving dish and garnish with extra thyme or parsley. Serve hot.

Delicious Variations

• Add cooked bacon or pancetta for a smoky, savory twist.
• Stir in a handful of baby spinach at the end for extra greens.
• Top with breadcrumbs and broil for a crispy gratin-style finish.
