Earthy sweet potatoes, meaty mushrooms, and vibrant spinach transform simple ingredients into a restaurant-worthy vegetarian dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 1 ½ lb | Medium-sized, peeled and cubed |
| Mushrooms 🍄 | 16 oz | Cream or baby bella, halved |
| Fresh Spinach 🌱 | 5 oz | Baby or regular, roughly chopped |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth of flavor |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, finely chopped |
| Smoked Paprika 🌶️ | 1 tsp | For subtle smoky depth |
| Olive Oil 🫒 | ½ cup | Extra-virgin for richness |
| Balsamic Vinegar 🍶 | 1 tbsp | For brightness and acidity |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher salt |

The sweet potatoes are the foundation here—organic sweet potatoes from the grocery store's produce section work perfectly, but if you find them at Whole Foods or a local farmers market, they'll have even better flavor. Look for ones that feel heavy for their size, with smooth, unblemished skin. The mushrooms can be any variety, but cremini or baby bella give the best texture when roasted. I usually grab mine from the Trader Joe's bulk section—they're consistently fresh and affordable. Fresh thyme is ideal, but if you're using dried, cut the amount to one-third of what's listed—it's much more concentrated.
No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch, though it won't be exactly the same. Short on balsamic vinegar? Apple cider vinegar gives a similar tang, or even a splash of lemon juice. The walnuts are optional but add such a nice contrast in texture—Trader Joe's sells them pre-toasted, which saves time. For the spinach, fresh is best, but frozen works in a bind (just thaw and drain well). If you're meal prepping, I'd skip the walnuts until serving—they go stale faster than the rest of the dish. The vegetable broth can be swapped for water, but the broth adds that extra depth that makes this dish feel special.
This dish reheats beautifully—3-4 days in the fridge, or freeze portions for up to 3 months. I like to portion it into glass containers with tight lids to maintain freshness. The flavors actually improve overnight as everything melds together. For extra crunch, toast your walnuts fresh before serving. If you're serving this as a main course, consider adding a sprinkle of nutritional yeast for a cheesy flavor without dairy. The dish keeps its vibrant colors best when stored properly, so avoid overcrowding the container.

Step-by-step instructions for roasted sweet potato mushroom and spinach
This method delivers perfectly caramelized sweet potatoes and umami-rich mushrooms with tender spinach.
🔥 Step 1: Roast Sweet Potatoes Until Caramelized
Preheat your oven to 400°F and line two baking sheets with parchment paper. Toss the 1.5 lb sweet potatoes with 2 tablespoons of the 0.5 cup olive oil, 0.5 teaspoon of the 1.5 teaspoon salt, and 0.25 teaspoon of the 0.5 teaspoon black pepper. Spread them in a single layer, leaving space between each piece.
Roast for 25-30 minutes, stirring once halfway through, until the edges are deep golden brown and the sweet potatoes are tender when pierced with a fork. The caramelization happens in the last 10 minutes, so don't remove them early. This step builds the foundation of flavor—don't skip the stirring to ensure even browning.
🍳 Step 2: Sauté Mushrooms and Garlic
While the sweet potatoes roast, heat 1 tablespoon of the remaining 0.5 cup olive oil in a large skillet over medium-high heat. Add the 16 oz mushrooms (halved) and cook for 6-8 minutes until they release their moisture and develop golden brown spots.
Push the mushrooms to one side of the pan and add the 4 cloves minced garlic. Stir for 30 seconds until fragrant—this prevents burning. Add the 1 teaspoon smoked paprika and 1 tablespoon fresh thyme, stirring constantly for 1 minute until the spices bloom. The mushrooms should be tender with crispy edges, and the garlic should add aromatic depth.
🥘 Step 3: Deglaze and Simmer with Broth
Pour in the 1 tablespoon balsamic vinegar and scrape up any browned bits from the bottom of the pan. Let it simmer for 2 minutes until slightly reduced. Add the 0.5 cup vegetable broth and bring to a gentle simmer, cooking for 3-4 minutes until the liquid reduces by half and coats the mushrooms.
Stir in the remaining 1 teaspoon salt and 0.25 teaspoon black pepper, then add the 5 oz chopped fresh spinach. Cook for 1-2 minutes until the spinach wilts completely. The mushrooms should be glossy and the sauce should cling to them—this is where the umami depth develops.
🥘 Step 4: Combine and Finish with Walnuts
Transfer the roasted sweet potatoes to the skillet with the mushroom-spinach mixture. Gently toss everything together, letting the sweet potatoes absorb the mushroom sauce for 1-2 minutes. The sweetness of the potatoes balances the earthy mushrooms perfectly.
Remove from heat and stir in the 0.25 cup toasted walnuts for added texture. Taste and adjust seasoning if needed—this dish should have a harmonious blend of sweet, earthy, and slightly smoky flavors. Serve immediately while the sweet potatoes are still warm and the spinach retains its vibrant color.
Pro Tips For Making Sweet Potato Mushroom And Spinach
- CUT SWEET POTATO IN EVEN SLICES: Thick chunks stay chewy, thin slices crisp faster—aim for ½-inch rounds. I used to eyeball it and ended up with half the pan looking undercooked while the rest turned to mush. A sharp knife and a ruler (yes, really) save time and frustration.
- SALT MUSHROOMS BEFORE COOKING: Toss sliced mushrooms with ½ teaspoon salt right after dicing—they’ll release moisture and brown better. I skipped this once and got sad, pale mushrooms that tasted bland no matter how much garlic I threw in later.
- WAIT FOR SPINACH TO WILT FULLY: Toss spinach in last and let it sit for 30 seconds after adding—it’ll collapse and soak up all the flavors. Rushing this step leaves you with a sad, half-wilted pile that looks like it was thrown in at the last minute.
- ROAST SWEET POTATO FIRST: Toss cubed sweet potatoes with oil and thyme, roast at 400°F (205°C) for 15 minutes before adding mushrooms and spinach. This jumpstarts the dish’s depth of flavor while you prep the rest—no waiting for everything to cook together. (Your nose will thank you.)

Nutrition facts
Frequently asked questions
Can I make this recipe with regular potatoes instead of sweet potatoes?
While you can substitute regular potatoes, the flavor and texture will be very different. Sweet potatoes provide natural sweetness and a creamier texture when roasted. If you must use regular potatoes, try Yukon Gold for better flavor, but expect a less caramelized result. The dish will still taste good, but the signature depth of flavor comes from the sweet potatoes.
How can I make this vegetarian dish vegan?
This recipe is already vegetarian, but to make it vegan, simply omit the walnuts or use toasted vegan-friendly nuts like almonds. Ensure your vegetable broth is vegan (no chicken base), and check that your smoked paprika doesn't contain any animal-derived additives. The dish will still be delicious and packed with plant-based nutrients!
What's the best way to store leftovers?
Store this dish in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze portions for up to 3 months. When reheating, warm in a skillet over medium heat with a splash of water or broth to restore moisture. The flavors actually improve overnight as everything melds together!
Can I add protein to make this a complete meal?
This dish pairs beautifully with grilled chicken, baked tofu, or even crumbled tempeh. For a seafood option, try adding pan-seared shrimp or white fish like cod. The earthy mushrooms and sweet potatoes complement protein perfectly, making it a satisfying main course.
Why does my spinach turn mushy when cooking?
Overcooking is the most common cause. Spinach wilts quickly—just 1-2 minutes over medium heat is perfect. Use fresh spinach and avoid stirring too vigorously. If using frozen spinach, thaw and drain it thoroughly first. The key is to cook it just until it softens but still maintains some texture.
