These roasted sweet potato halves bring together the best of summer produce with Mediterranean flair. The naturally sweet potatoes become tender and lightly caramelized in the oven, creating the perfect canvas for juicy cherry tomatoes and creamy mozzarella. A generous drizzle of fresh homemade basil pesto ties everything together with aromatic brightness.
This dish comes together in just 50 minutes with mostly hands-off cooking time. The pesto whips up quickly in a food processor while the sweet potatoes roast, making this an efficient weeknight option. Serve it as a satisfying vegetarian main course or as a stunning side dish at your next summer gathering.
The first time I made these sweet potatoes, it was a Tuesday evening and I had completely forgotten to plan dinner. I stared at some sweet potatoes on the counter and a container of cherry tomatoes that needed using, and somehow this combination happened. Now it is the dish my friends actually text me about later, asking when I will make it again.
Last summer I served these at a rooftop dinner with friends and watched everyone go quiet for that first bite. Someone actually asked if this was from a restaurant, which might be the best compliment a home cook can get on a random Tuesday night invention.
Ingredients
- 4 medium sweet potatoes: Scrubbed and halved lengthwise because the cut side caramelizes beautifully against the baking sheet
- 1 ½ cups cherry tomatoes: Halved so they release their juices slightly and meld with the cheese
- 200 g mozzarella balls: Bocconcini or ciliegine work perfectly here, halved for easy melting
- 1 cup fresh basil leaves: Packed tight because you want that pesto to be vibrant and fragrant
- ¼ cup toasted pine nuts: Walnuts make a perfectly fine substitute if pine nuts feel too expensive
- 1 garlic clove: One is enough since it will be raw in the pesto
- ¼ cup grated Parmesan: Adds that salty umami that makes pesto sing
- ½ cup extra virgin olive oil: Good quality matters here since it is the backbone of your sauce
- 2 tbsp olive oil for roasting: Helps those sweet potato edges get golden and crisp
- Salt and pepper: Your only seasonings, so do not be shy with them
- Fresh basil leaves: For garnish because extra basil never hurt anyone
Instructions
- Get your oven ready:
- Preheat to 200°C (400°F) and line a baking tray with parchment paper so cleanup is minimal later.
- Roast the sweet potatoes:
- Brush the cut sides with olive oil, season well, and place them cut-side down. Let them roast for 30 minutes until tender and the edges are caramelized.
- Make the pesto while you wait:
- Blend basil, pine nuts, garlic, Parmesan, salt, and pepper, then drizzle in the olive oil while the machine runs until smooth.
- Flip and top:
- Turn the sweet potatoes cut-side up and arrange cherry tomatoes and mozzarella on each half.
- Melt everything together:
- Return to the oven for just 5 minutes until the cheese softens and the tomatoes release their juices.
- Finish with pesto:
- Drizzle generously with your fresh pesto and scatter extra basil leaves on top before serving warm or at room temperature.
This recipe has become my go-to for summer nights when cooking feels like too much but I still want something that feels special and thoughtful.
Serving Suggestions
I love serving this alongside a simple green salad dressed with lemon and olive oil. The freshness balances the richness of the roasted sweet potatoes perfectly.
Make It Your Own
Sometimes I add roasted red peppers or grilled zucchini as extra toppings when I have them in the fridge. The recipe is forgiving and welcomes whatever summer vegetables you have on hand.
Pairing Ideas
A crisp Sauvignon Blanc cuts through the creamy mozzarella beautifully. For something non-alcoholic, sparkling water with plenty of lemon works just as well.
- Try adding a drizzle of balsamic glaze right before serving
- Toasted pumpkin seeds add nice crunch if you do not have nuts
- Leftover pesto keeps in the fridge for a week and works on everything
Summer on a plate, ready in under an hour.
Recipe FAQ
- → Can I make the pesto ahead of time?
-
Yes, the basil pesto can be prepared up to 3 days in advance and stored in an airtight container in the refrigerator. The top layer may darken slightly, but this doesn't affect the flavor. Just stir well before using.
- → What can I use instead of pine nuts?
-
Walnuts make an excellent budget-friendly substitute for pine nuts in the pesto. Cashews or almonds also work well. Toast whatever nuts you choose first to enhance their flavor before blending.
- → How do I know when the sweet potatoes are done?
-
The sweet potatoes are ready when they're tender all the way through when pierced with a fork. The cut side should be lightly caramelized and golden brown, usually after about 30 minutes at 200°C (400°F).
- → Can I use store-bought pesto instead?
-
Absolutely. Store-bought pesto works well in a pinch. Look for a refrigerated jar with minimal additives for the best flavor. You'll need roughly one jar for this recipe.
- → What other toppings work well with this dish?
-
Roasted red peppers, grilled zucchini ribbons, or artichoke hearts make excellent additions. For extra protein, consider adding white beans or chickpeas. Fresh arugula or spinach can add a nice peppery contrast.
- → Is this dish served hot or can it be eaten at room temperature?
-
It's delicious both ways. Serve it warm from the oven for melty mozzarella, or let it cool to room temperature—the flavors actually develop more as it sits. This makes it ideal for potlucks and picnics.
