Buckwheat Bake with Chicken and Spinach Recipe
This bake combines the flavor of buckwheat groats familiar from Polish dinners with tender chicken and spinach in a creamy sauce. It’s a good idea for a healthier oven-baked meal that’s still hearty and homey. It’s a bit like an Italian rice and chicken bake, but with the distinct, nutty taste of buckwheat.
This recipe uses traditional Polish buckwheat groats in a less obvious way than the classic “side for dinner”. It combines familiar local ingredients with the convenient, oven‑baked format of a casserole.
This bake combines the familiar taste of buckwheat groats with tender chicken and spinach in a creamy sauce, creating something between a Polish dinner and an Italian-style rice casserole. The nutty aroma of buckwheat contrasts beautifully with the creamy sauce and slightly garlicky spinach, while the browned cheese on top gives it a comforting, cozy feel. It’s clearly lighter than typical pasta bakes but still as satisfying as a solid home-cooked meal.
Why this version works
- Buckwheat cooked until fluffy keeps its structure and doesn’t turn into one solid block after baking.
- Thoroughly cooking off the liquid from the spinach prevents the sauce from becoming watery and pooling at the bottom of the dish.
- A mix of cream and stock creates a creamy but not heavy sauce that still tastes great when reheated.
Chef's tips
Cook the buckwheat so it’s loose and slightly firm – if you overcook it, it will turn into a dense block in the bake; it’s also good to let it steam off for a moment after cooking. Spinach, especially frozen, needs to cook off its excess moisture thoroughly in the pan, otherwise the sauce will be watery and won’t bind the buckwheat properly. Taste the spinach sauce before seasoning – nutmeg is intense, so add it literally a pinch at a time so it doesn’t dominate the whole dish.
How to serve
Serve the bake with a simple carrot and apple slaw or a mixed salad with a light vinaigrette to cut through the creaminess of the sauce. To drink, kefir, buttermilk or a delicate white wine work well if you’re serving it for a relaxed Sunday dinner. It’s also a convenient meal to pack in a lunchbox for work – it reheats well and keeps its structure.
Watch out for
- Don’t add too much nutmeg – it easily overwhelms the delicate flavour of the chicken and spinach.
- If the sauce in the pan is as thin as soup, cook it longer before mixing it with the buckwheat.
- Don’t overcook the chicken in the pan – if it’s very well done there, it will turn dry after baking.
Substitutions
- You can replace the chicken with turkey or leftover roasted meat from the previous day.
- You can swap part of the cream for milk; the sauce will be lighter but still creamy.
Ingredients
- buckwheat groats dry - 200 g
- chicken breast skinless - 400 g
- spinach fresh or frozen, chopped - 200 g
- onion medium - 1 piece
- garlic finely chopped - 2 cloves
- cream 30% or 18% fat - 200 ml
- vegetable stock can be made from a stock cube - 250 ml
- yellow cheese grated - 120 g
- oil for frying - 2 tablespoons
- butter for greasing the dish - 10 g
- nutmeg ground, optional - 0.25 teaspoons
- salt to taste
- black pepper to taste
Preparation
- Rinse the buckwheat groats in a sieve under running water. Cook in salted boiling water according to the package instructions (usually 12–15 minutes), until tender but still with a slight bite.
- After cooking, drain the buckwheat if needed and leave it in the sieve for a few minutes. Fluff with a fork so the grains stay loose rather than clumping together.
- Preheat the oven to 190°C (top and bottom heat). Grease a baking dish with butter, coating the bottom and sides with a thin layer so nothing sticks.
- Cut the chicken breast into small, even cubes. Season with salt and pepper, mix and set aside for a few minutes so the meat takes on the seasoning a little.
- Peel and finely dice the onion. Heat the oil in a large frying pan, add the onion and fry for 3–4 minutes until softened and slightly translucent, but not deeply browned.
- Add the chicken and fry for 6–8 minutes, stirring, until the pieces are white in the centre and lightly browned around the edges. There should be no visibly pink parts left.
- Add the chopped or pressed garlic and fry for about 1 more minute, stirring so it doesn’t burn and turn bitter.
- Add the spinach. If using frozen spinach, add it straight from the freezer and cook for 5–7 minutes, until completely thawed and most of the liquid has evaporated. If using fresh spinach, cook for 2–3 minutes until the leaves wilt and reduce in volume.
- Pour in the cream and stock, add nutmeg, salt and pepper. Cook for 5–7 minutes over medium heat, until the sauce thickens and turns creamy rather than watery; when you drag a spatula across the pan, it should briefly expose the bottom.
- Put the cooked buckwheat into a large bowl, add the contents of the pan and half of the grated cheese. Mix thoroughly until the buckwheat is evenly coated with the sauce and there are no dry clumps.
- Transfer the mixture to the baking dish, level the surface and sprinkle with the remaining cheese. The top should be evenly covered, with no patches of buckwheat showing through.
- Bake for 20–25 minutes, until the cheese melts and turns golden brown. After removing from the oven, leave the casserole to rest for 5–10 minutes so it firms up slightly – the portions should cut into neat pieces that don’t fall apart on the plate.
Storage
Store cooled leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave, covered, so the bake doesn’t dry out. You can also freeze individual portions for up to 2–3 months; thaw overnight in the fridge or reheat gently from frozen with a splash of stock or water.
I usually make this bake midweek when I have an open packet of buckwheat and a frozen chicken breast and don’t want to make plain “chicken with rice” again. I always save one piece for the next day’s lunch at work – eaten cold, it tastes a bit like a hearty buckwheat salad.
