Steps

Before you start
  • If using fresh beets, plan ahead—they take 35 minutes to roast
  • Have all ingredients prepped and measured before you begin stir-frying
  • Toast the walnuts while the beets roast to save time
  1. Prepare beetsOven 400°F / 205°C

    • Preheat oven to 400°F (200°C).
    • If using fresh beets, trim the greens, scrub, and lightly coat with 1 tbsp olive oil.
    • Wrap individually in foil and roast on a large rimmed baking sheet for 35–40 minutes, until a knife pierces the center with no resistance.
    • When cool enough to handle, peel with a paper towel or knife and cut into ¼-inch matchsticks or thin wedges.
    • If using vacuum-packed beets, simply peel and cut as described.

    Ready when: A knife pierces the center with minimal resistance

    Tip: Wear gloves while peeling to avoid staining your hands bright red

  2. Toast walnutsOven 350°F / 175°C

    • While beets roast, spread chopped walnuts on a separate section of the baking sheet or on a small skillet.
    • Toast at 350°F (175°C) for 7–9 minutes, stirring halfway through, until fragrant and lightly browned.
    • Transfer to a plate to cool and stop the cooking.
    • This step can happen at the same time as roasting the beets—just adjust oven racks accordingly.
    + Show details

    Ready when: Walnuts smell fragrant and are light golden brown

    Tip: Don't skip toasting—it brings out the walnut flavor and prevents a raw, astringent taste

  3. Cook buckwheat noodles

    • Bring a large pot of salted water to a boil.
    • Add buckwheat noodles and cook according to package directions (typically 4–6 minutes) until just tender but still with a slight chew.
    • Do not overcook or they will break apart.
    • Drain in a colander and set aside.
    • A light coating of oil prevents sticking.
    + Show details

    Ready when: Noodles are tender with a slight bite, not mushy

    Tip: Buckwheat noodles are delicate—stir gently and avoid aggressive draining to prevent breaking

  4. Make vinegar glaze

    • In a small bowl, whisk together red wine vinegar, Dijon mustard, and 2 tbsp minced garlic.
    • Season with a pinch of sea salt and black pepper.
    • If you prefer a slightly thinner glaze, add up to ¼ cup vegetable broth or water.
    • Set aside.
    + Show details

    Ready when: Mustard is fully dissolved and mixture is smooth

    Tip: Whisk the mustard in first to help emulsify the vinegar and prevent it from separating

  5. Stir-fry beets and aromatics

    • Heat 2 tbsp olive oil in a 12-inch (30 cm) skillet or wok over medium-high heat until shimmering.
    • Add the roasted beet matchsticks (or wedges) and remaining minced garlic.
    • Stir-fry for 2–3 minutes, tossing frequently, until beets are heated through and slightly caramelized at the edges.
    + Show details

    Ready when: Beets are hot and have light golden edges; fragrant garlic is no longer raw

    Tip: Keep the heat high enough to encourage light browning, but don't let the garlic burn—add it at the very end if you're concerned

  6. Add noodles and thyme

    • Pour the cooked buckwheat noodles into the skillet with the beets.
    • Add the fresh thyme leaves.
    • Toss everything together over medium-high heat for 1–2 minutes, breaking up any noodle clusters gently with two wooden spoons or tongs.
    + Show details

    Ready when: Noodles are evenly distributed and heated through; thyme fragrance is released

    Tip: Work gently to avoid breaking the delicate noodles—use tongs or two wooden spoons rather than a spatula

  7. Add glaze and toss

    • Pour the vinegar glaze over the noodle mixture and toss everything together for 1–2 minutes over medium heat, using gentle scooping motions to coat every strand.
    • The noodles will darken slightly as the vinegar reduces and coats them.
    + Show details

    Ready when: Noodles are evenly coated with glaze; liquid has mostly reduced

    Tip: Lower heat to medium so the vinegar doesn't evaporate too fast and the noodles don't stick to the pan

  8. Finish with walnuts and seasoning

    • Remove the skillet from heat.
    • Fold in the toasted walnuts, reserving a small handful for garnish.
    • Taste and adjust seasoning with sea salt and black pepper.
    • Transfer to a serving bowl or plates, top with reserved walnuts, and serve warm or at room temperature.
    + Show details

    Ready when: Walnuts are distributed throughout and dish is ready to serve

    Tip: Save some walnuts for garnish so each serving has visible crunch and the toasted flavor shines

Good to know

Tips
  • For vacuum-packed beets, look for ones with no added sugars or preservatives; drain and use immediately to save time
  • If fresh beets are unavailable or you're short on time, quality vacuum-packed beets taste nearly as good and add only 10 minutes to total prep
  • Serve at room temperature as a grain-free salad if desired, or warm for a more comforting main dish
  • For extra texture, add crispy fried shallots or breadcrumbs on top just before serving
Make ahead

You can roast the beets and toast the walnuts up to 2 days ahead and store separately in the refrigerator. Cook the noodles and prepare the glaze just before serving for best flavor and texture.

Storage & reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. The noodles may absorb more liquid as they sit, so stir in a splash of water or broth before reheating. Reheat gently in a skillet over medium heat, stirring occasionally, until warm. Do not freeze, as the noodle texture will deteriorate.

Substitutions
  • buckwheat noodles (soba or 100% buckwheat) → whole-wheat or regular wheat noodles. Use the same weight; cook according to package directions. The earthiness will be less pronounced, but the dish remains delicious
  • raw walnuts → toasted hazelnuts, pecans, or raw pumpkin seeds. Use the same volume; toast to bring out flavor. Each offers a different nuttiness or crunch
  • red wine vinegar → balsamic vinegar or sherry vinegar. Start with 1½ tbsp and adjust to taste—balsamic is sweeter and more complex; sherry is milder
  • fresh thyme leaves → fresh rosemary or oregano. Use the same amount; both provide an herbaceous note, though rosemary is more assertive
