The Story Behind My Favorite Garlic Butter Beet Recipe

A Little Rooted Nostalgia

I still remember the first time I cooked with beets on my own. Not the canned kind—those earthy, ruby-toned root vegetables that stain your hands magenta. My grandmother used to roast them in foil with just olive oil and salt. But I always wanted more… richness, depth, something to balance their earthy flavor. That’s when garlic butter entered the picture.

The very first time I tossed beet slices in warm, fragrant garlic butter, I was hooked. Roasting transformed them. The edges browned into a caramelized crunch while the centers softened into melt-in-your-mouth goodness. It reminded me of the roasted beet and feta salad I once tried at a cozy bistro, similar to this one you’ll love from Sylvia’s kitchen: Beet Salad with Feta, Cucumbers, and Dill.

Now, every fall when beets are abundant, this recipe becomes a go-to. It’s fast enough for weeknights but elegant enough for dinner parties.

What Makes These Beet Slices Special?

Most beet recipes lean heavily on vinegar or citrus. While that’s lovely, butter brings a different kind of magic. It wraps each slice in richness. Garlic and thyme amplify the savory notes. The result? A side dish that feels gourmet with hardly any effort.

Not to mention, it pairs wonderfully with other beet-forward recipes like Roasted Beets and Sweet Potatoes with Feta and Cilantro—try serving them together for a colorful, seasonal platter.

Beets 4 medium Peeled and sliced into 1/4-inch rounds
Unsalted Butter 3 tbsp Melted
Garlic 2 cloves Minced finely
Olive Oil 1 tbsp Helps roast and crisp the edges

Kitchen Tools You’ll Use

You don’t need any special equipment, just the basics:

  • Sharp chef’s knife – for slicing the beets thin and evenly

  • Cutting board – preferably non-porous (beets stain!)

  • Baking sheet – large enough to spread beet slices in one layer

  • Parchment paper – keeps cleanup easy and prevents sticking

  • Small mixing bowl – for whisking the garlic butter

  • Pastry brush or spoon – to coat each slice evenly

Substitutions & Variations

  • Butter: Swap with ghee or vegan butter for dairy-free.

  • Thyme: Try rosemary, oregano, or sage for variation.

  • Garlic: Roasted garlic puree can be used for a milder twist.

Cooking Instructions & Foolproof Tips

Step-by-Step Instructions

  1. Prep your oven and baking sheet

    • Preheat the oven to 400°F (200°C). Line a baking sheet with parchment.

  2. Make the garlic butter mixture

    • In a small bowl, combine melted butter, olive oil, minced garlic, thyme, salt, and pepper.

  3. Slice and arrange the beets

    • Slice peeled beets into 1/4-inch rounds. Lay them out in a single layer on the baking sheet.

  4. Brush with garlic butter

    • Use a brush or spoon to generously coat both sides of each beet slice.

  5. Roast and flip

    • Roast for 30–35 minutes, flipping halfway through. The edges should caramelize beautifully.

  6. Garnish and serve

    • Sprinkle with chopped parsley or chives before serving warm.

Expert Tips for Best Results

  • Consistency is key: Slice beets evenly for uniform cooking.

  • Don’t overcrowd: Give each slice room to breathe so it crisps, not steams.

  • Use golden or Chioggia beets: For a colorful twist with milder flavor.

  • Save the tops: Beet greens make a great side sautéed with garlic.

Serving Ideas, Storage, & Pairings

What Pairs Well with Garlic Butter Beets?

These beet slices are surprisingly versatile. They shine next to proteins or as part of a plant-based plate.

How to Store & Reheat

  • Refrigerate: Keep in an airtight container for up to 4 days.

  • Freeze: While not ideal, they can be frozen in a single layer then bagged. Texture may soften.

  • Reheat: Oven at 350°F for 8–10 minutes brings back the crisp edges. Avoid microwaving—they’ll steam.

Frequently Asked Questions

Can I use pre-cooked beets?
Yes, but you’ll miss out on the caramelization. Raw beets are best for roasting.

Are beet skins safe to eat?
Absolutely! Just scrub them well. For this recipe, peeled beets allow better butter absorption.

Can I prep them ahead?
Definitely. Slice and marinate them in the garlic butter up to a day in advance.

Are these low-carb or keto-friendly?
Beets are moderate in carbs. Great for balanced diets but not strict keto.

What herbs besides thyme work well?
Rosemary, oregano, or even dill add lovely layers of flavor.
