- 1 tsp celery salt
- 2 tbsp tomato paste (or replace with roasted red pepper puree)
- 1 tbsp all-purpose flour

- 4 medium potatoes peeled, cut into chunks

About the ingredients
Method
- Heat olive oil over medium heat in a large skillet until shimmering but not smoking. Season thighs well both sides with salt and pepper. Place skin side down. Listen for that sizzle—don't crowd the pan or they steam. Brown undisturbed 6 to 8 minutes until deep golden crust forms. Flip; brown other side 5 to 7 minutes. Remove to plate. Skin color darkens; crust should lift from pan easily.
- Lower heat to medium-low. Add butter to skillet melt until foaming. Toss in onions. Cook stirring occasionally 4 to 5 minutes till softened, edges translucent, some browning—onions releasing sugars. Add garlic, celery salt, tomato paste or pepper puree. Stir vigorously coating onions. Sprinkle flour; mix constantly to avoid raw taste. Cook 45 seconds; pale roux forms bubbling gently but don’t scorch. Flour keeps sauce thick, binds liquids.
- Turn heat to low. Slowly pour chicken bouillon and water, stirring to combine, scraping browned bits stuck to pan bottom with wooden spoon—those little black flecks hold flavor bombs. Toss in bay leaves. Simmer 2 to 3 minutes until sauce thickens; coats back of spoon. Sauce should look glossy, thick but pourable, no raw flour lumps.
- In slow cooker base, spread potatoes and carrots evenly. Pour onion-tomato mixture over veg, do not stir. Layer browned chicken thighs skin side up over top; skin prevents meat from drying, crisps slightly in steam. Cover slow cooker.
- Cook on high for about 3 hours. Meat tender, juices run clear. Potatoes fork-tender but not mushy; carrots sweetened and soft. Pull out bay leaves before serving. If underdone, chicken will resist easily with fork or skin not taut. Adjust time 15 minutes up or down, depending on model.
- Serve hot straight from slow cooker with pan juices spooned over. Skins may not be crispy—broil briefly if desired. Leftovers reheat well; sauce thickens in fridge. Add splash water when reheating.
Cooking tips
Chef's notes
- 💡 Brown chicken carefully skin side down no crowding pan sizzling sound critical. Golden crust forms in 6-8 minutes. Skip flipping too soon or chicken sticks, messes skin. Heat medium not high to avoid burnt bits. Sear builds flavors, don’t rush.
- 💡 When adding butter and onions reduce heat medium-low. Butter foams before onions go in. Stir occasionally watch for translucent edges and light browning. Garlic and tomato paste last to reduce bitterness but coat well. Sprinkle flour slow, stir 30-45 seconds or roux tastes raw.
- 💡 Pour liquids slow on low heat scrape all browned bits with wooden spoon. Those dark flecks pack flavor. Simmer till sauce thickens to light coating on spoon back. Too thin means longer cook; too thick add water or broth. Texture beats timer here.
- 💡 Layer veggies evenly in slow cooker base. Pour sauce over no stirring. Then chicken skin side up on top. Skin keeps moisture locked in plus crisps in steam. Avoid flipping chicken now or skin soggy. Potatoes and carrots take equal time; season well beforehand.
- 💡 Cooking time varies by slow cooker model—open at 2 and half hours check fork tenderness and juice clarity. If chicken resists fork or skin not taut add 15 more mins. Overshoot means mushy potatoes and dry meat. Bay leaves must come out after cooking; bitter if left.
- 💡 Butter can swap ghee if dairy free but loses richness. Tomato paste replaced with roasted red pepper puree for smoky sweet twist, try both. Use low sodium bouillon or broth over plain water to keep flavor intact. Good olive oil matters avoid cheap or oil smokes fast.
Common questions
How to know when chicken thighs done?
Meat juices run clear, skin taut. Press with fork; resists means underdone. Listen for sizzle in skillet step signs crust. Slow cooker timing depends on model best check early. Color changes key too.
Can flour be skipped for sauce?
Sauce then thinner, watery often bland. Can thicken later with cornstarch slurry after slow cooking. But flour makes that pale roux flavor; add slowly avoid lumps raw taste if rushed.
What if chicken sticks in pan while browning?
Wait longer crust forms it will release. Don’t poke early gently shake pan also makes lift easier. Use good quality non-stick or cast iron for best surface. Moving too soon tears skin.
How to store leftovers?
Keep tightly covered fridge few days; sauce thickens fridge add splash water warming. Can freeze in airtight container up to 3 months; thaw overnight in fridge. Reheat gentle low or microwave stir periodically.
