Roasted Beets With Caramelized Onions and Feta: A Symphony of Sweet and Savory

My grandmother, a formidable woman with a green thumb and an even sharper wit, always grew beets in her garden. As a child, I wasn’t their biggest fan, but she’d roast them until their earthy sweetness intensified, then toss them with tangy vinegar, sweet onions, and salty feta. The vibrant colors and contrasting flavors somehow transformed these humble root vegetables into something truly special. It wasn’t just a side dish; it was a testament to her resourcefulness and the magic she could create with simple ingredients. Now, whenever I make this dish, I’m instantly transported back to her sun-drenched kitchen, the scent of roasting beets filling the air.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour 5 minutes
• Servings: 4
• Yield: Varies based on beet size
• Dietary Type: Vegetarian (can be made vegan by omitting feta)

Ingredients

• 2 tablespoons cider vinegar
• 2 teaspoons coarse Dijon mustard
• 1 teaspoon salt (or to taste)
• Black pepper (lots of black pepper!)
• 3 tablespoons olive oil
• 1 lb yellow sweet onion, quartered lengthwise then cut into about 1-inch pieces
• 1 teaspoon sugar
• 15 whole fresh small beets, peeled (roasted or boiled, or use as many beets as you wish)
• 4 ounces crumbled feta cheese (or to taste)
• Toasted walnuts (optional)

Equipment Needed

• Large bowl
• Whisk
• Large skillet
• Aluminum foil (for roasting beets)
• Oven

Instructions

1. If using fresh beets, preheat your oven to 400°F (200°C). Wrap the peeled beets individually in aluminum foil. This helps them steam and cook evenly. Roast for about 30 minutes, or until they are just fork-tender. Alternatively, you can boil the beets until tender. Let cool slightly.
2. Once the beets are cool enough to handle, quarter them if they are large, and halve them if they are small.
3. In a large bowl, whisk together the cider vinegar, Dijon mustard, salt, and plenty of black pepper. Don’t be shy with the pepper – it complements the sweetness of the beets and onions beautifully.
4. In a slow, steady stream, whisk in the 3 tablespoons of olive oil, whisking continuously until the dressing is well combined and emulsified. This will create a lovely, balanced vinaigrette.
5. In a large skillet, heat about 3-4 tablespoons of olive oil over medium heat. Add the quartered sweet onions and 1-2 teaspoons of sugar. The sugar helps to caramelize the onions, bringing out their natural sweetness.
6. Cook the sweet onions until they are golden brown and softened, about 15-18 minutes, stirring frequently to prevent burning. Season with salt and pepper to taste. The onions should be sweet, savory, and meltingly tender.
7. Add the cooked beets, browned onions, and feta cheese to the dressing in the bowl.
8. Stir gently to combine, making sure not to overmix and break down the beets too much. You want to keep their shape and texture intact.
9. Sprinkle with toasted walnuts, if desired, for added crunch and nutty flavor.

Expert Tips & Tricks

• Roasting vs. Boiling Beets: Roasting the beets intensifies their flavor and concentrates their natural sugars. Boiling is faster, but you’ll sacrifice some of that deep, earthy sweetness.
• Caramelizing Onions Perfectly: The key to perfectly caramelized onions is low and slow cooking. Don’t rush the process! Stir frequently and add a splash of water if they start to stick or burn.
• Make-Ahead Tip: You can roast the beets and caramelize the onions a day or two in advance. Store them separately in the refrigerator and combine them with the dressing and feta just before serving.
• Peeling Beets Easily: After roasting or boiling, plunge the beets into a bowl of ice water. The skins will slip right off!
• Adjusting Sweetness: Taste the dressing and adjust the sugar and vinegar to your liking. If the beets are particularly sweet, you may need less sugar in the onions.

Serving & Storage Suggestions

This roasted beet salad is delicious served warm or cold. It makes a fantastic side dish alongside grilled chicken, fish, or a vegetarian main course. You can also add it to a bed of mixed greens for a hearty salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. The beets may bleed a little, staining the feta, but the flavor will still be delicious. Reheat gently in a skillet or microwave before serving, or enjoy cold. This dish is best served fresh.

FAQs (Frequently Asked Questions)

A: While fresh beets are preferred for their superior flavor and texture, you can substitute two 15-ounce cans of drained small whole beets, halved or quartered if large. Just be aware that the flavor will be less intense.

Q: How do I prevent my hands from getting stained when working with beets?
