The skillet gets crowded fast when the beef goes in, and that’s the moment to resist the urge to rush. Browning the cubes in batches gives them room to build a dark crust instead of steaming, and those browned bits become part of the sauce once the wine hits the pan. That’s the difference I notice most in this slow cooker beef bourguignon: the finished gravy tastes layered, not just like broth that’s been sitting with meat.
I build the sauce right in the same skillet, with the carrots and onion, tomato paste, flour, and wine. Scraping up the sticky bits as the wine simmers brings the flavor into the slow cooker, while the flour helps give the cooking liquid body. The beef turns tender over the long cook, and the mushrooms and pearl onions go in near the end so they keep their shape. What you get is a rich, savory stew with tender beef and a glossy, wine-dark sauce.

Kitchen Note
At the end, I test a beef cube with a fork rather than relying on the clock alone. It should give easily but still hold together; if it’s not there yet, keep cooking on the same setting until it is.
Save this slow cooker beef bourguignon for a cozy dinner with tender beef, mushrooms, and a deep red-wine gravy.
Why the Slow Cooker Can’t Build the Beef’s Browning for You
A slow cooker is excellent at turning a well-marbled cut tender, but it won’t give the beef a browned surface. That happens in the skillet, where dry cubes meet hot oil and have room to sear. If the pan is packed, the beef releases moisture and steams; the batches take longer, but they leave you with the browned edges and savory residue that make the sauce taste like it started with more than liquid.
The skillet work also connects the flavors instead of leaving them in separate layers. The carrots and yellow onion soften in the same pan, and the tomato paste cooks briefly before the flour goes in. When the wine simmers, it lifts the fond from the bottom of the skillet. Scrape thoroughly, including the corners, so that concentrated flavor doesn’t stay behind when you pour the mixture over the beef and bacon.
That’s why I don’t skip the stovetop portion even though the slow cooker does most of the cooking. It’s a short stretch of active work that gives the long, gentle cook a more complete base. The finished sauce should taste savory and rounded, with the wine integrated rather than sharp.
What the Beef, Wine, and Late-Added Vegetables Bring to the Pot

- Beef chuck — Chuck has enough connective tissue and marbling to become tender during the slow cook without losing its beefy character. Cut it into even 1 1/2-inch cubes so the pieces finish at about the same time; very lean cuts don’t give the sauce the same richness and are more likely to turn dry. If you buy a whole chuck roast, cut it yourself for more consistent pieces.
- Bacon — Regular diced bacon supplies smoky flavor and the drippings used to start the beef and vegetables. A standard grocery-store bacon works well; an expensive specialty bacon isn’t necessary. Leaving it out makes the stew less smoky and less savory, so I keep it in for the classic result.
- Dry red wine — Choose a dry red such as Merlot, Cabernet Sauvignon, or Pinot Noir; an inexpensive bottle you’d be comfortable drinking is enough. Sweet wine can push the sauce in the wrong direction. If you need to cook without wine, use the same amount of beef broth instead; the sauce will be milder and won’t have wine’s acidity and depth.
- All-purpose flour — It thickens the skillet base as it cooks with the tomato paste and vegetables. Stir it in well and give it the full minute so it doesn’t leave a raw flour taste. For a gluten-free version, use the cornstarch method in the variations below rather than swapping flour directly into the skillet.
- Cremini mushrooms and frozen pearl onions — Cremini mushrooms bring an earthy note, while pearl onions add sweetness in distinct, tender bites. White button mushrooms work in the same amount and can be quartered the same way. The frozen pearl onions are convenient and go straight into the slow cooker from the freezer; there’s no need to thaw them first.
Build the Wine Sauce Before the Slow Cooker Takes Over
Render the Bacon, Then Brown the Beef
Cook the diced bacon in a 12-inch skillet over medium heat for 6 to 8 minutes, stirring occasionally, until crisp. Transfer it to a 6-quart slow cooker and leave about 1 tablespoon of drippings in the skillet. Pat the beef dry, season it with kosher salt and black pepper, then heat the vegetable oil over medium-high heat. Brown the beef in batches for 3 to 4 minutes per side and transfer each batch to the slow cooker; if the pieces crowd one another, work in another batch rather than piling them up.
Soften the Vegetables and Cook the Flour
Add the carrots and chopped yellow onion to the skillet and cook over medium heat for 5 minutes, stirring occasionally. They should begin to soften, with the onion losing its raw, sharp look. Stir in the minced garlic and tomato paste for 1 minute, then sprinkle in the flour and stir for another minute. Keep the flour moving so it coats the vegetables instead of clumping in one spot.
Deglaze and Pour the Sauce
Pour in the dry red wine and scrape the skillet bottom until the browned bits loosen. Let it simmer for 3 to 4 minutes; the sharp smell of raw wine should mellow as it bubbles. Stir in the beef broth, dried thyme, and bay leaf, then pour the mixture over the beef and bacon. The beef should be covered in the sauce mixture, though the slow cooker doesn’t need to be filled to the top.
Slow-Cook the Beef, Then Finish with Vegetables
Cover and cook on LOW for 7 to 8 hours or HIGH for 3 1/2 to 4 hours, until the beef is nearly fork-tender. Stir in the quartered mushrooms and frozen pearl onions, cover again, and cook on LOW for 1 to 1 1/2 hours or HIGH for 45 to 60 minutes. The vegetables should be tender and the beef fork-tender at the end. Remove the bay leaf before serving.
Two Practical Ways to Adapt This Bourguignon
Make It Gluten-Free with a Cornstarch Slurry
Leave out the all-purpose flour. Before adding the broth to the skillet, whisk 1 1/2 tablespoons cornstarch into 1/4 cup of the listed beef broth until smooth, then stir the remaining broth into the wine mixture and pour it over the beef. Add the slurry to the slow cooker with the sauce. The gravy will thicken without the flour, though it may look a little glossier.
Leave Out the Bacon for a Beef-Forward Version
Skip the bacon and use the listed tablespoon of vegetable oil to brown the beef. Continue with the carrots and onion in the skillet, scraping up the beef’s browned bits as they cook. The stew will lose the bacon’s smoky flavor and rendered richness, but the wine, beef, and thyme still make a savory sauce.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for 3 to 4 days. The sauce will thicken as it chills, and the beef may feel firmer when cold.
- Freezer: Freeze in airtight containers for up to 3 months. Thaw overnight in the refrigerator; the mushrooms may soften a little after freezing.
- Reheating: Warm gently in a covered saucepan, stirring occasionally, or heat in the microwave and stir partway through. Reheat leftovers to 165°F, and avoid a hard boil that can break the beef into shreds.
