Air Fryer Charred Radish Dill Buckwheat
A vibrant Eastern European-inspired buckwheat side dish combining nutty roasted groats with caramelized onions, charred radishes, and fresh dill. The air fryer creates deep color on the radishes while keeping the buckwheat tender and fluffy. This pairs beautifully with roasted meats or can stand alone as a vegetarian grain bowl.

Steps
Before you start
- Preheat air fryer to 400°F (200°C) for 5 minutes
- Have the caramelized onions ready (use store-bought or prepare ahead)
- Use toasted buckwheat groats (kasha) rather than raw for better flavor
Char the radishesOven 400°F / 205°C
- Place halved radishes in a bowl and toss with 2 tablespoons (30 ml) of olive oil, a pinch of sea salt, and freshly cracked black pepper.
- Arrange them cut-side down in the air fryer basket in a single layer.
- Air fry at 400°F (200°C) for 18–20 minutes, shaking the basket halfway through.
- The radishes should be deeply charred on the cut side and tender when pierced with a fork.

Ready when: Radishes are deeply browned on cut side and fork-tender
Tip: Cut radishes to similar size so they cook evenly; cut-side down creates the deepest char
Toast the buckwheat
- While radishes cook, heat 1 tablespoon (15 ml) of olive oil in a medium saucepan over medium-high heat.
- Add the buckwheat groats and toast for 3–4 minutes, stirring constantly, until fragrant and beginning to turn golden.
- This awakens the nutty flavor.

Ready when: Groats smell nutty and are light golden in color
Tip: Stir constantly to prevent burning; toasted groats create a deeper, richer flavor than untoasted
Cook the buckwheat
- Pour 3 cups (720 ml) of vegetable broth into the saucepan with toasted buckwheat.
- Bring to a boil, then reduce heat to medium-low, cover with a lid, and simmer for 12–15 minutes until buckwheat is tender and the broth is absorbed.
- The grains should be fluffy but not mushy.

Ready when: Buckwheat is tender, broth is completely absorbed, and grains fluff easily with a fork
Tip: Don't stir the buckwheat once simmering—this helps keep grains separate and fluffy
Combine and finish
- Remove the saucepan from heat.
- Stir in the charred radishes, caramelized onions, fresh dill, butter (if using), and a final taste of sea salt and black pepper.
- Toss gently until evenly combined, then let sit covered for 2–3 minutes to warm through and meld flavors.

Ready when: All components are evenly distributed and warm
Tip: Add dill just before serving to preserve its bright, fresh flavor; fold gently to avoid breaking radish pieces
Good to know
Tips
- For deeper char on radishes, pat them dry after cutting to remove excess moisture before tossing with oil
- Toasted buckwheat groats (kasha) are widely available at Eastern European markets and many supermarkets—they taste far better than raw groats for this dish
- If your air fryer runs hot, start checking radishes at 15 minutes to prevent over-charring
- Serve warm or at room temperature; this dish is equally good as a side dish or grain salad base
Make ahead
Caramelized onions can be made up to 3 days ahead and stored in an airtight container in the refrigerator. Buckwheat can be cooked up to 1 day ahead, then gently reheated with a splash of broth on the stovetop just before serving. Char the radishes fresh just before serving for the best texture and color.
Storage & reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over medium-low heat with a splash of vegetable broth (about 2–3 tablespoons per serving) for 3–4 minutes, stirring occasionally. Do not freeze, as buckwheat becomes mushy upon thawing. Best enjoyed fresh.
Substitutions
- toasted buckwheat groats (kasha) → Pearl barley or farro. Use the same weight and cooking method; both have a hearty texture and will take about the same time to cook
- fresh dill, finely chopped → Fresh parsley or tarragon. Parsley is milder; tarragon offers a slight anise note. Use the same amount; add just before serving
- fresh radishes → Baby turnips or beets. Turnips mimic radishes' mild bite; beets add earthiness. Cook for the same time, but beets may need 2 extra minutes
- vegetable broth → Chicken or mushroom broth. Chicken broth adds richness; mushroom broth deepens the umami. Use 1:1 ratio
