Ingredients

Roasted Sweet Potatoes

• Olive oil (1 tbsp): Helps the potatoes roast evenly and develop color
• Kosher salt (½ tsp): Enhances the natural sweetness

Creamy Garlic Mushroom & Spinach Filling

• Butter (2 tbsp): Adds richness and helps brown the mushrooms
• Olive oil (1 tbsp): Prevents butter from burning
• Cremini mushrooms, sliced (4 cups): Earthy, meaty texture that builds savory depth
• Shallot, minced (1 small): Mild onion flavor that blends smoothly into the sauce
• Garlic cloves, minced (2): Aromatic backbone of the dish
• All-purpose flour (1 tbsp): Lightly thickens the sauce so it clings to the filling
• Vegetable broth (½ cup): Adds savory body without heaviness
• Heavy cream or half-and-half (½ cup): Creates a silky, luxurious sauce
• Kosher salt (¾ tsp) & black pepper (½ tsp): Essential seasoning
• Nutmeg (pinch): Subtle warmth that enhances the cream
• Baby spinach (5–6 cups): Wilts into the sauce for color and freshness
• Dijon mustard (1 tsp): Adds gentle tang and depth
• Lemon juice (1 tsp): Brightens and balances the cream
• Parmesan, finely grated (¼ cup, optional): Adds salty, nutty finish

How to Make Creamy Garlic Mushroom & Spinach Stuffed Sweet Potatoes

Roast the Sweet Potatoes

Preheat the oven to 425°F. Slice the sweet potatoes lengthwise, rub with olive oil, and season with salt. Place cut side down on a lined baking sheet and roast for 35–45 minutes until very tender with caramelized edges. Tip: Cut-side-down roasting steams the inside while caramelizing the surface.

Brown the Mushrooms

Heat a large skillet over medium-high heat. Melt the butter with olive oil, then add mushrooms in an even layer. Cook 6–8 minutes, stirring only once, until deeply browned. Tip: Browning first prevents a watery sauce and builds savory flavor.

Build the Sauce

Add the shallot and cook 1 minute until softened. Stir in garlic and cook 30 seconds until fragrant. Sprinkle in the flour and stir for 30 seconds to lightly toast it. Slowly add broth, then cream, stirring constantly. Simmer 2–3 minutes until glossy and slightly thick. Season with salt, pepper, and nutmeg.

Add Spinach and Finish

Add spinach and toss until wilted, about 1–2 minutes. Stir in Dijon and lemon juice. Remove from heat and fold in Parmesan if using.

Assemble

Flip the roasted sweet potatoes cut side up and gently mash the centers with a fork. Spoon the creamy mushroom–spinach mixture generously over each half. Serve hot, optionally garnished with parsley.

Tips for Success

• Brown mushrooms thoroughly before adding liquids
• Keep sauce gently simmering to avoid splitting
• Adjust thickness with a splash of broth if needed
• Add acid at the end to keep the dish from tasting heavy

Equipment Needed

• Sheet pan with parchment paper
• Heavy skillet (cast iron or stainless steel works best)
• Sharp knife and cutting board
• Wooden spoon or spatula

Recipe Variations

• Dairy-Free: Use olive oil instead of butter and coconut cream in place of dairy
• Protein Boost: Stir in white beans or shredded rotisserie chicken
• Greens Swap: Use thinly sliced kale instead of spinach, sautéing a few minutes longer

Serving Suggestions

Serve with a crisp green salad, roasted broccoli, or crusty bread. Finish with cracked black pepper, fresh herbs, or a drizzle of chili crisp for heat.
