Ingredients You’ll Need

This recipe uses straightforward ingredients that blend beautifully—rich butter, fragrant thyme, and sharp Parmesan elevate sweet potatoes into something special. Shopping tip: Choose thin, long sweet potatoes as they cook evenly and smash nicely without falling apart.

• Olive oil spray: Helps achieve that perfect crisp without extra grease.
• Sweet potatoes: Opt for long and thin ones for uniform cooking and smashing ease.
• Unsalted butter: Melting it lets you coat the potatoes evenly with all those lovely seasonings.
• Kosher salt: Enhances natural sweetness and balances flavors.
• Freshly ground black pepper: Adds a subtle heat to contrast the sweetness.
• Garlic powder: Provides gentle, aromatic depth without overpowering.
• Onion powder: Complements the garlic with savory richness.
• Fresh thyme: Its earthy, slightly minty notes meld perfectly with the potatoes and cheese.
• Freshly grated Parmesan cheese: Offers nutty, salty crust when broiled that I can’t get enough of.
• Nonfat Greek yogurt (optional): Adds a cool, tangy creaminess if you want an extra touch when serving.

Variations

I love mixing things up with the Savory Smashed Sweet Potatoes with Parmesan and Thyme Recipe—it’s a great base for personalization. Feel free to tweak the herbs or swap cheeses to match whatever you’re craving or what’s in your fridge.

• Mozzarella swap: I sometimes sprinkle shredded mozzarella instead of Parmesan for a gooey, melty twist that kids adore.
• Rosemary instead of thyme: Using fresh rosemary gives it a piney, more intense aroma that’s lovely for fall dinners.
• Dairy-free option: Leave out the Parmesan and replace butter with olive oil to keep it vegan and still flavorful.
• Spicy kick: Add a pinch of smoked paprika or chili flakes to the seasoning mix for a smoky heat I enjoy on chillier evenings.

How to Make Savory Smashed Sweet Potatoes with Parmesan and Thyme Recipe

Step 1: Prepare and Slice the Sweet Potatoes

Start by preheating your oven to 425°F and spraying a sheet pan with olive oil spray to prevent sticking. Rinse your sweet potatoes well and dry them thoroughly—this helps them crisp better later. Then slice each potato into ¾-inch thick rounds; it’s key that they’re even so they cook uniformly. I like to lay them out as soon as I slice to keep things organized.

Step 2: Season and Roast Until Tender

In a large mixing bowl, whisk together melted butter, kosher salt, freshly ground black pepper, garlic and onion powders, plus chopped fresh thyme. Toss your potato rounds gently but thoroughly to coat every piece in that golden, flavorful mixture. Spread them out in one even layer on your prepared pan—crowding causes steaming rather than roasting. Bake for about 25 minutes, or until you can easily pierce the potatoes with a fork. This is your cue that they’re perfectly tender but still hold together.

Step 3: Smash, Broil, and Add Cheese

Once baked, let the sweet potatoes rest for 5 minutes to cool slightly—it makes smashing much easier. Adjust the oven rack to the second highest setting and switch to broil on high. Using a fork, gently press down on each round until it’s smashed flat but still in one piece; I find that using the tines of the fork in a cross pattern works best. Lightly spray the smashed slices with olive oil spray again, then sprinkle grated Parmesan cheese generously on each. Place them under the broiler for 3–5 minutes until the cheese melts and the edges crisp up. Keep a close eye so they don’t burn!

Step 4: Garnish and Serve

When your smashed sweet potatoes come out of the oven, sprinkle with a bit more fresh thyme for aroma and a small dollop of Greek yogurt if you like a tangy contrast. I find this final touch elevates the whole dish. Serve warm and watch how quickly these disappear from the table.

Garnishes

I usually top these smashed sweet potatoes with extra fresh thyme leaves and a tiny dollop of cool Greek yogurt—it adds such a nice contrast to the crispy, cheesy surface. Sometimes I also sprinkle a bit of crushed red pepper flakes if I want a subtle heat. A drizzle of honey is another unexpected but delicious touch when I want a sweet-savory combo.

Side Dishes

These potatoes pair beautifully with roasted chicken or grilled fish for a balanced meal. Sometimes I’ll serve them alongside a fresh green salad or sautéed greens like spinach or kale to add color and freshness. For a cozy dinner, they go great with meatloaf or a vegetarian lentil loaf.

Creative Ways to Present

For special occasions, I’ve arranged them on a rustic wooden board garnished with sprigs of thyme and small ramekins of dipping sauces like garlic aioli or herb yogurt dip. Layering the smashed sweet potatoes slightly overlapping creates a beautiful, inviting spread. It’s a flower-like pattern that really impresses my dinner guests every time.

Make Ahead and Storage

Storing Leftovers

I store leftover smashed sweet potatoes in an airtight container in the fridge, and they stay surprisingly good for up to 3 days. To avoid sogginess, I let them cool completely before sealing, and I place parchment paper between layers if stacking is necessary.

Freezing

Freezing works well if you lay the cooled smashed potatoes in a single layer on a baking sheet first and freeze until firm, then transfer them to a freezer bag. This way, they won’t stick together and reheat better. I’ve frozen and thawed them with no major loss in texture—just re-crisp under the broiler once thawed.

Reheating

To bring leftovers back to life, I find reheating in a 375°F oven for 10-15 minutes works best. This revitalizes their crispiness, especially if you broil them for a minute or two at the end. Avoid microwaving as it tends to make them soggy.
