FAQs
Can I use frozen grapes or sweet potatoes?
Fresh grapes and sweet potatoes work best for this recipe because they roast evenly. Frozen grapes may become too mushy, and frozen sweet potatoes can release excess moisture, affecting texture.
Can I prepare this dish ahead of time?
Yes, you can toss the ingredients together and refrigerate for up to 2 hours before roasting. However, for best texture and flavor, roast shortly after mixing.

- 3 cups California grapes
- 1 pound orange sweet potatoes, peeled and cut into 1/4-inch width slices
- 3/4 cup thinly sliced onion
- Freshly ground pepper to taste

Instructions
- Preheat Oven: Heat your oven to 425°F (220°C) to prepare for roasting the ingredients evenly and achieving a crisp caramelization.

- Arrange on Baking Sheet: Spread the coated mixture on a large baking sheet in a single layer. This allows for even roasting and browning of the grapes and sweet potatoes.
- Roast: Place the baking sheet in the preheated oven and roast for 30 minutes or until the sweet potatoes become tender. Stir or toss the mixture halfway through the cooking time to promote even cooking and prevent sticking.

- Use red or green grapes depending on preference; red grapes tend to caramelize slightly more.
- For an extra hint of sweetness, drizzle a little honey before roasting.
- Make sure to slice sweet potatoes uniformly to ensure even cooking.
- This dish is great served alongside roasted meats or as part of a vegetarian meal.
