Why This Recipe Works

One-step searing: Browning the bacon and beef directly on a sheet pan under the broiler gives you caramelized flavor without babysitting a skillet.
Root-veg upgrade: Parsnips roast into sweet, velvety coins while squash lends body, so you don’t need extra thickeners.
True slow cooking: Ten hours on low melts collagen into silk; the beef stays fork-tender but never mushy.
Built-in side: Because the vegetables cook in the gravy, dinner is complete with nothing more than crusty bread.
Freezer-friendly: Make a double batch; leftovers freeze flat in zip bags for up to three months.
Holiday worthy: Deep red wine sauce, aromatic herbs, and jewel-toned veg look gorgeous in a Dutch-oven serving dish for parties.
Flexible timing: If you’re running late, it holds beautifully on “warm” for up to two extra hours without drying out.

Ingredients You'll Need

Great beef bourguignon starts with the right beef. Look for well-marbled chuck roast—intramuscular fat equals flavor. If you can, buy a whole roast and cube it yourself; pre-cut “stew beef” often contains irregular sizes that cook unevenly. For the wine, use a mid-range Burgundy or any dry Pinot Noir you’d happily drink; cooking concentrates flaws, so skip the “cooking wine” aisle.

Thick-cut bacon renders the perfect amount of fat for browning. Turkey bacon works in a pinch, but you’ll want to add a tablespoon of avocado oil to compensate. Parsnips become honey-sweet after hours in wine; choose medium ones—thick woody cores can be fibrous. If parsnips aren’t available, carrots are fine, but reduce the brown sugar by half. Butternut squash holds its shape, but acorn or even pumpkin chunks work—just keep them around 1-inch so they don’t dissolve into baby food.

Pearl onions are traditional, yet frozen, pre-peeled ones save sanity. Tomato paste in a tube is worth the splurge; you’ll use a tablespoon here and won’t waste a whole can. Finally, bouquet garni means “garnished bouquet”—a leek leaf wrapped around thyme, parsley stems, bay, and peppercorns—easy to fish out later.

How to Make Slow Cooker Beef Bourguignon with Parsnips and Winter Squash

Broiler-Sear Bacon & Beef

Position oven rack 6 inches from broiler; line a rimmed sheet pan with foil. Lay 6 oz diced bacon in an even layer; broil 3 minutes until edges curl. Pat 3½ lbs chuck cubes dry, season with 1 Tbsp kosher salt and 2 tsp pepper; scatter over bacon. Broil 8–10 minutes, stirring once, until beef is deeply browned but not cooked through. Transfer everything (including rendered fat) to slow-cooker insert—those caramelized bits equal free flavor.

Build the Base

Add 2 cups frozen pearl onions, 3 minced garlic cloves, 2 Tbsp tomato paste, and 2 Tbsp flour to the insert. Stir until the tomato paste coats everything in a rusty film; the flour will thicken the sauce as it simmers.

Deglaze with Wine & Stock

Pour in one 750 ml bottle Pinot Noir plus 1 cup low-sodium beef stock. Use a wooden spoon to scrape the sheet pan directly into the cooker—every browned morsel counts. The liquid should just cover the meat; add an extra ½ cup stock if needed.

Season & Herb Bundle

Stir in 1 Tbsp brown sugar, 1 tsp fish sauce (umami bomb—trust me), and nestle your bouquet garni: 4 thyme sprigs, 2 parsley stems, 1 bay leaf, and ½ tsp peppercorns wrapped in a leek leaf and tied with kitchen twine.

Low & Slow Magic

Cover and cook on LOW 8 hours. Resist peeking; trapped steam is your ally. The meat will go from tough to buttery as collagen breaks down into gelatin.

Add the Vegetables

At hour 8, slide the lid, discard bouquet garni, and stir in 3 cups 1-inch butternut squash cubes and 2 cups ½-inch parsnip rounds. Re-cover and cook 1–2 hours more, until vegetables are tender but still hold shape.

Skim & Finish

Tilt the insert and ladle off excess fat (a fat separator works wonders). Taste; adjust salt, pepper, or a splash of balsamic for brightness. Sauce should coat a spoon. If too thin, simmer on high 15 minutes with the lid ajar.

Serve Like a Pro

Ladle over mascarpone mashed potatoes or egg noodles; garnish with chopped parsley for color. Offer crusty bread to swipe the plate clean.

Expert Tips

Overnight Flavor Boost

Prep through Step 4 the night before; refrigerate insert. Next morning, add wine/stock and start the cooker—flavors meld like a 24-hour chili.

De-Fatting Hack

Chill finished stew 30 minutes; fat solidifies into a disk you can lift off. Reheat gently and you’ve got restaurant-level clarity.

Halve or Double

Cooker must be ½–¾ full for proper heat circulation. Halve in a 3-qt, double in a 7-qt; same cook time.

Non-Alcoholic Swap

Replace wine with 2 cups grape juice + 1 cup beef stock and 1 Tbsp red-wine vinegar for acidity. Flavor differs but still luscious.

Quick-Cool for Safety

Divide hot stew into shallow containers; ice-bath for 20 minutes before refrigerating to dodge the 40–140 °F danger zone.

Egg Noodle Secret

Toss noodles with a spoonful of the stew sauce before plating; they absorb flavor and stay silky, not sticky.

Variations to Try

Mushroom Medley: Swap half the parsnips for cremini and shiitake; add during the last hour so they stay meaty.
Smoky Bacon-Free: Use 2 tsp smoked paprika + 2 Tbsp olive oil for a vegetarian version; substitute beef with 3 lbs portobello caps cut in 2-inch chunks and use mushroom stock.
Spiced Orange: Add 2 strips orange peel and ¼ tsp ground cloves to the bouquet garni for a Provençal holiday vibe.
Speedy Pressure-Cooker: Follow steps 1–4 in an Instant Pot, then cook on high pressure 35 minutes with natural release 15 minutes. Add vegetables and pressure-cook 3 minutes more.
Low-Carb: Replace squash with diced turnips and swap parsnips for rutabaga; net carbs drop to ~9 g per serving.

Storage Tips

Refrigerate: Cool completely, transfer to airtight containers, and refrigerate up to 4 days. The flavors actually improve on day two once the wine mellows.

Freeze: Portion into quart zip-top bags, press out air, label, and freeze flat up to 3 months. Thaw overnight in the fridge; reheat gently with a splash of broth to loosen.

Make-Ahead for Entertaining: Cook fully, refrigerate, then reheat in a 300 °F oven, covered, 45 minutes. Garnish with fresh parsley just before guests arrive for that “I just slaved all day” illusion.

Frequently Asked Questions

You can, but you’ll sacrifice the fond (browned bits) that give the sauce depth. If you’re in a rush, brown half the beef in the slow-cooker insert on the stovetop over medium-high heat, then proceed.

Dice larger (1¼-inch) and add during the final hour. If your cooker runs hot, switch to “warm” after vegetables are added; residual heat will finish them gently.

Yes, but the flavor will be lighter. Bolster it with 1 tsp soy sauce or miso for extra umami.

Swap the flour for 1 Tbsp cornstarch whisked into cold stock; the rest of the ingredients are naturally gluten-free. Serve over rice or potatoes.

Insert a fork; it should slide in with almost no resistance, but the chunk should still hold together. If it shreds, it’s over-cooked—delicious but not classic.

Yes, but ensure the insert is at least half full for proper heat retention. Cooking time remains the same.
