Introduction

Sheet Pan Roasted California Grapes and Sweet Potatoes combine the natural sweetness of grapes and tender sweet potatoes with tangy balsamic vinegar and fresh basil. This simple, vibrant dish is perfect as a cozy weeknight side or a crowd-pleaser at gatherings.

A metal baking tray filled with a mix of roasted sweet potato wedges, deep purple-red grapes, and thin slices of red onion, all cooked to a slightly crisp texture with light charring on the edges. The orange sweet potatoes are scattered in uneven chunks across the tray, interspersed with round, plump grapes that appear juicy, and slightly wilted, curled red onion strips. Bright green herb leaves are sprinkled over the mix, adding a fresh contrast. A metal spatula rests on the tray’s lower right corner, partially under some vegetables. The tray sits on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Ingredients

3 tablespoons extra virgin olive oil
3 tablespoons balsamic vinegar
3/4 teaspoon sea salt
3 cups California grapes
1 pound orange sweet potatoes, peeled and cut into 1/4-inch slices
3/4 cup thinly sliced onion
Freshly ground pepper to taste
Snipped fresh basil

Instructions

Step 1: Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper or lightly grease it.
Step 2: In a large bowl, combine the olive oil, balsamic vinegar, and sea salt. Add the sweet potato slices, grapes, and sliced onion, tossing gently to coat evenly.
Step 3: Spread the mixture in a single layer on the prepared sheet pan, making sure the ingredients are evenly distributed for proper roasting.
Step 4: Roast in the preheated oven for about 30-35 minutes, stirring halfway through, until the sweet potatoes are tender and slightly caramelized and the grapes are soft.
Step 5: Remove from the oven and season with freshly ground pepper to taste. Sprinkle snipped fresh basil over the top before serving to add a bright, herbal note.

Tips & Variations

For extra flavor, add a sprinkle of crushed red pepper flakes before roasting for a subtle spicy kick.
Try using different colored California grapes—red, green, or black—for varied sweetness and visual appeal.
Substitute sweet potatoes with butternut squash or carrots for a different texture and flavor.
Serve this dish warm or at room temperature; it pairs beautifully with roasted meats or as part of a vegetarian meal.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently in the oven at 350°F (175°C) for 10-15 minutes or microwave until heated through. This helps maintain the dish’s texture and flavor.

How to Serve

A sheet pan filled with three main layers of roasted ingredients: orange sweet potato wedges placed unevenly around the pan with a slightly crispy texture, scattered bright red grape clusters that add round shapes and pop of color, and thin slices of purple-red onion spread throughout, adding curly, soft textures. Small pieces of green herbs are sprinkled on top, adding freshness and contrast. A metal spatula with a wooden handle rests on the pan near the bottom right. The pan sits on a white marbled surface.
