Beets are a vegetable people often love or avoid, but when prepared well they reveal a deep, natural sweetness. Roasting enhances the sugars in root vegetables, and beets become mellow, lightly sweet, and tender. My husband and I enjoy beets throughout late summer and fall, preparing them in many different ways. Nutritionally they are excellent — rich in folate, manganese, copper, and provide fiber along with vitamin A and vitamin C. They’re a simple way to add color, texture, and nutrients to a meal.
This recipe pairs roasted beets with oven-baked red onions. Baking both together concentrates their sweetness and softens their texture, creating a balanced side dish that complements grilled or roasted meats, and works well on a composed antipasti platter. I used a mix of golden and red beets to add visual contrast, but you can use all red beets if that’s what you have. A finishing sprinkle of chopped parsley adds freshness; crumbled goat or feta cheese is an optional addition that pairs beautifully with the beets’ sweetness.

Sweet and Sour Roasted Beets and Onions
Serves 4
15 minutes
2 hours
2 hours 15 minutes
A versatile side dish for roasted meats or part of an antipasti spread. Simple, forgiving, and full of flavor.
Ingredients
- 6 medium beets
- 2 medium red onions (leave whole with skins on)
Dressing:
- 1/3 cup olive oil
- 2 tablespoons red wine vinegar
- 1 tablespoon honey
- 2 teaspoons capers
- Salt and freshly ground black pepper, to taste
- 1/4 cup chopped fresh parsley
Instructions
- Preheat the oven to 375°F (190°C). Use a medium casserole dish with a lid or cover the dish with foil.
- Wash the beets well, trimming the tops if they are attached but leaving the skin intact. Place the beets and the whole red onions (skins on) in the casserole dish in a single layer.
- Cover the dish and roast in the preheated oven until the beets are fork-tender, about 1 to 1 1/2 hours depending on their size. The onions should also soften and concentrate in sweetness.
- Remove the dish from the oven and allow the vegetables to cool until they are comfortable to handle. Cooling makes peeling easier and helps the flavors settle.
- Peel the beets (the skins should slip off after roasting) and cut them into 1/2-inch wide strips. If you used a mix of golden and red beets, cut each variety the same size for even presentation.
- Peel the roasted onions and slice them into 1/3-inch pieces. Roasted onions will be soft and mildly sweet; handle gently to keep pieces intact.
- Combine the beet strips and sliced onions in a serving bowl. Toss gently to mix textures and colors.
- In a separate small bowl, whisk together the olive oil, red wine vinegar, honey, capers, and a pinch of salt and pepper until the dressing is emulsified. Taste and adjust seasoning as needed.
- Pour the dressing over the warm beets and onions, then toss lightly to coat. The warm vegetables will absorb the dressing and take on a glossy finish.
- Stir in the chopped parsley just before serving. Serve at room temperature alongside roasted meats or as part of an antipasti selection. Optionally, crumble goat or feta cheese over the top when serving for a creamy, tangy contrast.
