There’s a certain magic that happens when the air turns crisp and the leaves begin to turn. The hustle of summer barbecues gives way to the quiet comfort of bubbling stovetops and slow cookers, and suddenly every cozy sweater in your closet feels like an invitation to stay home and cook something wonderful. This slow cooker beef and winter squash stew with roasted garlic is my love letter to that moment. I first developed it on a blustery Sunday when the farmers’ market was bursting with gnarly squash in every shade of sunset and the butcher had just cut a beautiful batch of chuck roast into perfect, marble-y chunks. I wanted a dish that required no babysitting—just honest ingredients, gentle heat, and time. Ten hours later, the scent drifting through the house was so intoxicating that my neighbor knocked on the door to ask what I was making. One spoonful and you’ll understand why: silky butternut and hearty beef, mellow roasted garlic, a whisper of thyme, and the deep, wine-kissed broth that tastes like Sunday night by the fire. Whether you’re feeding a crowd after apple-picking, meal-prepping for a busy week, or simply craving a bowl that feels like a weighted blanket, this stew delivers.

Why This Recipe Works

Hands-off comfort: The slow cooker does the heavy lifting while you live your life.
Two-step depth: A quick stovetop sear on the beef creates caramelized fond that enriches the broth.
Sweet-savory balance: Roasted garlic and squash add natural sweetness that plays beautifully against the umami-rich beef and tomato paste.
Week-night friendly: Chop the veggies the night before; in the morning, just layer and go.
Freezer hero: Leftovers freeze beautifully for up to three months—perfect for future “I don’t feel like cooking” days.
One-pot nutrition: Each bowl delivers protein, fiber-rich veg, and slow-release carbs for satisfying, all-day energy.

Ingredients You'll Need

Great stew starts at the grocery store. Look for chuck roast that’s bright red with plenty of white marbling—those thin veins of fat melt into unctuous goodness after hours of gentle simmering. If you can, ask the butcher to cut it into 1½-inch pieces for you; uniform chunks cook evenly and save prep time. For the winter squash, butternut is reliable and easy to peel, but kabocha or red kuri squash bring an extra-creamy texture and edible skin. Pick one that feels heavy for its size and has a matte, unblemished rind. Roasting the garlic tames its bite and turns the cloves into savory candy; choose firm, tight heads with no green sprouts. Yukon gold potatoes hold their shape yet still lend creaminess, while tomato paste deepens color and adds sweet acidity. A modest pour of dry red wine lifts every flavor without screaming “booze.” Finally, invest in good beef stock or broth—low-sodium lets you control seasoning.

Substitutions: Swap beef for bison or lamb stew meat if you’d like a gamier note. Sweet potatoes can stand in for Yukon golds, and if wine isn’t your thing, replace it with an equal amount of stock plus 1 tablespoon balsamic vinegar for brightness. Vegetarians can substitute two cans of drained chickpeas and vegetable stock, though cooking time will drop to 4–5 hours on low.

How to Make slow cooker beef and winter squash stew with roasted garlic

Roast the garlic

Preheat oven to 400°F. Slice the top quarter off two whole heads of garlic to expose the cloves. Drizzle with olive oil, wrap loosely in foil, and roast 35–40 minutes until cloves are caramelized and jammy. Cool slightly, then squeeze out the cloves into a small bowl and mash with a fork.

Sear the beef

Pat 3 lbs chuck roast cubes dry and season generously with kosher salt and cracked black pepper. Heat 1 tablespoon canola oil in a heavy skillet over medium-high heat until shimmering. Brown beef in batches, 2–3 minutes per side; transfer to slow cooker. Deglaze pan with ½ cup red wine, scraping browned bits, then pour over beef.

Build the base

Add roasted garlic paste, 2 tablespoons tomato paste, 2 bay leaves, 1 teaspoon dried thyme, 1 teaspoon smoked paprika, and 2 tablespoons Worcestershire sauce to the slow cooker. Stir to coat beef in the flavor-packed mixture.

Add vegetables & liquid

Pile on 4 cups cubed butternut squash, 1½ cups diced Yukon gold potatoes, 1 cup sliced carrots, 1 chopped onion, and 2 ribs sliced celery. Pour in 3 cups low-sodium beef stock and remaining wine. Liquid should just reach the top of the solids—add water or stock if needed.

Slow cook

Cover and cook on LOW 8–9 hours or HIGH 4–5 hours, until beef shreds easily with a fork and squash is silky. Avoid lifting the lid during cooking; steam loss can extend cook time.

Finish and season

Remove bay leaves. Stir in 1 cup frozen peas for color and sweetness. Taste; add salt, pepper, or a squeeze of lemon for brightness. Let peas heat through 5 minutes.

Serve

Ladle into deep bowls over mashed potatoes, buttered egg noodles, or crusty bread. Garnish with chopped parsley or micro-greens for a fresh pop.

Expert Tips

Brown = flavor

Don’t crowd the beef while searing; moisture trapped between cubes will steam rather than brown, robbing the stew of its rich fond.

Freeze roasted garlic

Roast extra heads, mash, and freeze in teaspoon portions. Instant umami bomb for future soups, mashed potatoes, or salad dressings.

Low and slow wins

Whenever possible, choose LOW setting. Collagen breaks down gradually, turning tough beef into spoon-tender morsels without drying edges.

Thickening trick

If you prefer a thicker gravy, ladle ½ cup hot broth into a small jar with 2 tablespoons flour; shake until smooth, stir back into stew, cook 15 minutes on HIGH.

Overnight prep

Assemble everything in the removable crock the night before, cover, and refrigerate. In the morning, set it on the base and hit START—no extra effort.

Safe temperature

Beef should reach at least 205°F for optimal tenderness. Use an instant-read thermometer if you’re unsure; adjust cook time as needed.

Variations to Try

Moroccan spice

Add 1 teaspoon each ground cumin and coriander plus ½ teaspoon cinnamon. Stir in ½ cup chopped dried apricots with the peas.

Mushroom lover

Replace potatoes with 2 cups baby portobello mushrooms; add 1 tablespoon soy sauce for extra earthiness.

Smoky heat

Add 1 chipotle pepper in adobo, minced, and ½ teaspoon smoked paprika. Finish with a squeeze of lime and chopped cilantro.

Storage Tips

Refrigerator: Cool stew completely, transfer to airtight containers, and refrigerate up to 4 days. Flavors deepen overnight, making leftovers even tastier.

Freezer: Portion into freezer-safe zip bags, press out excess air, label, and freeze flat up to 3 months. Thaw overnight in refrigerator before reheating.

Reheating: Warm gently in a saucepan over medium-low, adding a splash of stock to loosen. Microwave works in a pinch; use 50% power to prevent beef from toughening.
