Steps

Before you start

Preheat oven to 425°F (220°C) and roast the pumpkin pieces 25–30 minutes ahead so they cool slightly before blending
Measure out buckwheat groats and vegetable broth in advance
Fresh sage is essential; dried sage will turn bitter in the slow cooker

1
Roast the pumpkinOven 425°F / 220°C
- Preheat oven to 425°F (220°C).
- Toss the 1.5 lb (680 g) of pumpkin cubes with 2 tbsp (30 ml) olive oil, ½ tsp (3 g) kosher salt, and a pinch of black pepper on a 9×13-inch (23×33 cm) rimmed baking sheet.
- Spread in a single layer and roast for 25–30 minutes, stirring once halfway through, until the pumpkin is very tender and the edges are lightly caramelized.
- Remove from oven and let cool for 5 minutes.

Ready when: Pumpkin is tender and edges are lightly caramelized
Tip: Cut pumpkin into uniform 1-inch cubes so they roast evenly; pat dry before roasting to help them brown
2
Blend pumpkin into purée
- Transfer the roasted pumpkin (about 1 cup / 240 ml when fully cooked) to a blender or food processor.
- Add ¼ cup (60 ml) of the vegetable broth and blend until completely smooth, about 1 minute.
- If the mixture is too thick, add another 2–3 tbsp (30–45 ml) broth.
- Set aside.

Ready when: Purée is completely smooth with no lumps
Tip: Don't overblend; a smooth purée takes only about 1 minute
3
Combine buckwheat and broth in slow cooker
- Pour the rinsed buckwheat groats into a 4- to 5-quart (3.8–4.7 L) slow cooker.
- Add the remaining 2¾ cups (660 ml) of vegetable broth (3 cups total minus what was used in blending).
- Stir well to combine.
- Cover and cook on low for 1 hour.

Ready when: Buckwheat is partially tender and some liquid remains
Tip: Rinse buckwheat thoroughly before adding to remove any dust or debris
4
Stir in pumpkin purée and seasonings
- Open the slow cooker and stir in the pumpkin purée, ¼ tsp (0.5 g) freshly grated nutmeg, and three fresh thyme sprigs.
- Season lightly with kosher salt and black pepper (about ¼ tsp each to start).
- Stir thoroughly to incorporate the pumpkin.
- Cover and continue cooking on low for 1 hour more.

Ready when: Mixture is creamy; buckwheat grains are soft but not mushy
Tip: Fresh thyme helps balance the sweetness of pumpkin; remove sprigs before serving if you prefer
5
Add cream and final adjustments
- Uncover the slow cooker and stir in ¾ cup (180 ml) of cold heavy cream in a slow, steady stream, stirring constantly to prevent lumping.
- The cream will immediately begin warming and the mixture will become silky.
- Taste and adjust seasoning with additional salt and pepper as needed.
- The buckwheat should be tender and the overall texture creamy but not soupy.

Ready when: Cream is fully incorporated and mixture is uniform and creamy
Tip: Add cream slowly while stirring to avoid any curdling or lumps; cold cream prevents shocking the warm buckwheat
6
Fry sage in brown butter
- While the slow cooker finishes, melt 3 tbsp (43 g) unsalted butter in a small 8-inch (20 cm) skillet over medium heat.
- Once melted, add the fresh sage leaves (about ¾ cup / 12 g loosely packed) and cook gently for 2–3 minutes, stirring occasionally, until the sage is crispy and the butter turns golden brown with a nutty aroma.
- Do not let the butter or sage scorch.
- Remove from heat immediately.

Ready when: Sage is crispy, butter is golden brown and nutty-smelling
Tip: Watch the butter carefully; it can go from golden to burnt very quickly. Have a cool surface ready to transfer the skillet if needed
7
Plate and garnish
- Divide the creamy pumpkin and buckwheat mixture among six serving bowls or plates.
- Top each portion with a generous spoonful of the crispy sage and brown butter (including some of the broken sage leaves and butter).
- Serve immediately while the buckwheat is warm and the sage is still crispy.

Tip: Don't stir the sage and brown butter into the buckwheat; keep it as a topping so the sage stays crispy

Tips

Fresh sage is non-negotiable: dried sage becomes bitter and overpowering in slow cooking. If you don't have fresh sage, substitute with crispy prosciutto or pancetta and use fresh thyme or parsley as garnish.
Buckwheat groats can smell earthy or slightly nutty out of the package, which is normal. Rinsing removes excess starch and helps prevent the finished dish from becoming gluey.
This dish is naturally vegetarian and pairs beautifully with roasted chicken, turkey, or as part of a vegetarian Thanksgiving table. It also works well alongside sautéed kale or roasted Brussels sprouts.
Slow cookers vary in temperature; if your buckwheat is not tender after 2 hours on low, continue cooking in 15-minute increments. Older or larger groats may need up to 2.5 hours total.

Make ahead

You can roast the pumpkin and make the purée up to 1 day ahead; store it in an airtight container in the refrigerator. Rinse and measure the buckwheat the night before. The assembled dish can be held in the slow cooker on warm for up to 30 minutes after finishing, but the texture is best served fresh.

Storage & reheating

Refrigerate leftovers in an airtight container for up to 3 days. The sage and brown butter are best made fresh, but any unsauced buckwheat mixture can be gently reheated in the microwave with a splash of broth or cream. To reheat, spoon into a bowl, cover loosely, and microwave on 50% power for 2–3 minutes, stirring halfway. Prepare fresh crispy sage to serve on top. Not recommended for freezing due to the cream.

Substitutions

buckwheat groats (hulled) → steel-cut oats or wild rice blend. Oats will cook faster (reduce slow-cooker time to 1.5 hours total); wild rice takes slightly longer. Both absorb liquid similarly and pair well with pumpkin.
heavy cream, cold → full-fat Greek yogurt or crème fraîche. Add at the very end and stir gently; yogurt and crème fraîche should not simmer for long or they may separate.
fresh sage leaves, whole → crispy pancetta or prosciutto bits. Cook separately until crisp, then use brown butter alone as the finishing sauce. This shifts the flavor profile but is equally delicious.
freshly grated nutmeg → freshly grated ginger or ¼ tsp ground cinnamon. Ginger adds warmth and a slight spice; cinnamon is more autumnal. Use about half the amount if substituting with cinnamon.
