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
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
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.

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
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.

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
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.

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
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.

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
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.

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
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.

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
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.

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
