A one-pot Seafood recipe with Russian flavors, built for busy weeknights when you want real food without a sink full of dishes. Comes together in roughly 41 minutes, serves about 4, and uses ingredients you can find at any normal grocery store. The technique is simple: build a base in your pot, layer in the main ingredients, simmer until everything has had time to talk to each other, and serve straight from the pan. If you're cooking for picky eaters, this one tends to land — the flavors are recognizable, the texture is comforting, and there's nothing weird hiding in the ingredient list. Perfect for the kind of evening where you want dinner on the table by 7pm and the kitchen empty by 7:30.

Step-by-step instructions

In a medium pot, heat the olive oil over medium-high heat. Add the onions and cook, stirring occasionally until the onions start to caramelize. Add the carrots and cook until the carrots start to soften, about 4 more minutes.
Add the stock, water, potatoes, bay leaves, and black peppercorns. Season with salt and bring to a boil. Reduce heat, cover and cook for 10 minutes. Add the millet and cook for 15 more minutes until millet and potatoes are cooked.
Gently add the fish cubes. Stir and bring the soup to a simmer. The fish will cook through very fast, so make sure to not overcook them. They are done when the flesh is opaque and flakes easily.
Garnish the soup with chopped fresh dill or parsley before serving.

Why this works on a weeknight

Fish Soup (Ukha) genuinely fits a 30-minute weeknight window, which is why it earned a spot in our Quick Soups & Stews collection. The technique is forgiving, the ingredient list is grocery-store standard, and the active cooking time is short enough that you can answer a text message in the middle without ruining dinner.

Cleanup notes

This is a single-pan recipe, so the cleanup is exactly one pan, one cutting board, and one knife. While the dish rests, fill the pan with hot soapy water — by the time you are done eating, the residue lifts off with a single pass of a sponge. Skip the steel wool on cast iron; a stiff brush and warm water are all you need to keep the seasoning intact.

Make-ahead and leftovers

Leftovers keep covered in the fridge for up to three days. Reheat in a dry pan over medium-low with a splash of water or stock to loosen the sauce. Fish Soup (Ukha) actually improves overnight as the flavors keep talking to each other, so doubling the recipe and packing tomorrow's lunch is a high-leverage weeknight move.
