The first time I made this cozy casserole, my daughter—who had declared squash “too mushy”—asked for thirds. It was a frigid January afternoon, the kind that makes your bones feel like glass, and I needed dinner to cook itself while we built the world’s most lopsided snowman. I tossed tender chicken thighs, jewel-bright butternut squash, and a handful of pantry staples into my slow cooker, hoping the alchemy of low heat and time would turn skepticism into supper. Six hours later the house smelled like sage and apple and Sunday supper at Grandma’s, even though Grandma was 400 miles away. We ate straight from the crock, steam fogging the kitchen windows, and I mentally high-fived my past self for hiding an extra cup of greens under the cheese. That night I scribbled “winner—blog ASAP” in my recipe journal. Here we are, three winters later, still making it weekly because it tastes like comfort, cooks like a dream, and somehow gets better for lunch the next day. If your people think they don’t like squash, this is the recipe that will convert them—no lecturing, just juicy chicken bathed in sweet-savory gravy that begs for crusty bread.

Frequently Asked Questions

Yes, but add 1 extra hour on low and place frozen thighs on top so they thaw in the steam rather than water-logging the veggies.

Nope. If you roast squash halves first, the flesh scoops out easily; for cubes, peel because the skin stays tough in a slow cooker.

High for 3 hours works, but the squash may not break down into that silky gravy. If rushed, cube squash smaller and check at 2.5 hours.

Not at all—smoked paprika gives warmth, not heat. Add ¼ tsp cayenne if your crew likes a gentle kick.

Absolutely—use an 8-quart slow cooker; cook time remains the same. You may need to stir in an extra ½ cup stock at the end for desired consistency.

Crusty whole-grain bread, garlicky sautéed kale, or a crisp apple-walnut salad with maple vinaigrette.

Chicken should reach 175 °F for fall-apart tenderness, and squash should smash easily with a fork. If in doubt, cook 30 more minutes on low—slow cookers are forgiving.

Yes! Layer everything except stock and quinoa in the insert, cover, and refrigerate. In the morning, add cold stock and start the cooker.
