Ingredients

To make this incredible French Onion Pot Roast, gather these simple yet powerful ingredients. You’ll transform humble components into a gourmet-tasting meal!

• 1 (2 pound) chuck roast
• 2 tablespoons butter
• A splash of oil (like olive or vegetable)
• 3 cloves minced garlic
• 2 large onions, thinly sliced
• 2 cups beef broth
• 1 tablespoon EACH Worcestershire sauce AND apple cider vinegar
• ½ teaspoon onion powder
• ½ teaspoon dried thyme
• 1 bay leaf
• ⅛ teaspoon celery seeds (crushed between fingers)
• 1 tablespoon sugar
• 2-3 tablespoons cornstarch
• ⅓ cup water

Notes & Substitutions

Selecting the right ingredients ensures the best results for your tender pot roast recipe.

• Chuck Roast: A chuck roast is ideal for this recipe due to its marbling and connective tissue, which breaks down during long cooking, making the beef incredibly tender. You can use a bone-in chuck roast, but adjust cooking time as needed. Other cuts like rump roast or bottom round can work, but may be slightly less tender.
• Onions: Yellow onions are perfect here for their balance of sweetness and sharpness, caramelizing beautifully. White onions also work well, offering a slightly milder flavor.
• Vinegar: Apple cider vinegar brightens the dish and cuts through the richness. White wine vinegar or red wine vinegar are excellent substitutes, adding similar acidity.
• Celery Seeds: These tiny seeds add a subtle, earthy, and savory note that enhances the overall flavor profile. If you don’t have them, you can omit them without ruining the dish, but they add a special touch to this deep, comforting beef dish.
• Fresh Herbs: While dried thyme and a bay leaf are specified, feel free to use fresh herbs. A sprig of fresh thyme or a few sprigs of parsley added towards the end of cooking can brighten the flavors.

Equipment

You don’t need fancy tools to make this hearty French Onion Pot Roast. Here’s what helps:

• Large Skillet or Dutch Oven: Essential for searing the beef and sautéing onions. A Dutch oven is ideal if you’re using the oven method.
• Slow Cooker: A 3-quart or 6-8 quart slow cooker works perfectly for the slow cooker method.
• Small Bowl or Mason Jar: For mixing the cornstarch slurry.

Slow Cooker Instructions

Prepare the Roast: Pat your chuck roast dry with paper towels. Season generously on all sides with salt and pepper.

Sear the Beef: Heat a large skillet over medium-high heat. Add the butter and a splash of oil. Once the butter melts and sizzles, add the chuck roast to the skillet. Sear on all sides for about 2-3 minutes per side until deeply browned. Browning the meat significantly adds to the flavor and tenderness of the final pot roast recipe. Remove the seared roast to a plate.

Sauté Onions (Optional but Recommended): Add a little more oil to the pan if needed. Sauté the thinly sliced onions for 3-4 minutes, or until they soften slightly. This quick step deepens their flavor.

Assemble Slow Cooker: Place half of the sautéed onions (or raw if skipping sautéing) into the bottom of your slow cooker. Add all the minced garlic, beef broth, Worcestershire sauce, apple cider vinegar, onion powder, dried thyme, bay leaf, celery seeds (crushed between your fingers), and sugar. Place the seared chuck roast into the slow cooker. Top with the remaining onions.

Cook Low and Slow: Cover the slow cooker. Cook on the LOW setting for 6-8 hours. For fall-apart tender results, I recommend cooking for the full 8 hours. The beef should easily shred with a fork.

Thicken Gravy: Carefully remove the cooked chuck roast from the slow cooker and transfer it to a plate. Cover it loosely with foil to keep it warm. In a small bowl or mason jar, whisk together 2 tablespoons of cornstarch with the ⅓ cup of water until smooth (this is your slurry). Pour the slurry into the slow cooker, stirring well.

Let it cook for an additional 5-7 minutes, stirring occasionally, until the gravy thickens to your liking. If it’s still too thin, mix the remaining tablespoon of cornstarch with 2 tablespoons of water, add to the slow cooker, and cook for another 5 minutes.

Serve: Shred or slice the beef and return it to the thickened gravy.

Oven Instructions

Prepare the Roast: Pat your chuck roast dry with paper towels and season generously on all sides with salt and pepper.

• Sear in Dutch Oven: Heat a Dutch oven (or a large, oven-safe pot with a lid) over medium-high heat. Add the butter and a splash of oil. When the butter melts and crackles, add the chuck roast. Sear on all sides for about 2-3 minutes per side until deeply browned. Remove the seared roast to a plate.

• Sauté Onions (Optional but Recommended): Add a little more oil to the Dutch oven if needed. Sauté the thinly sliced onions for 3-4 minutes, or until they soften slightly.

• Assemble Dutch Oven: Return the seared chuck roast to the Dutch oven. Add the minced garlic, 2 cups of beef broth, Worcestershire sauce, apple cider vinegar, onion powder, dried thyme, bay leaf, celery seeds, and sugar. The liquid should come halfway up the chuck roast; add more broth if necessary to achieve this. Stir gently to combine the liquids and seasonings around the roast.

• Braise in Oven: Position a rack in the center of your oven and preheat to 275ºF (135ºC). Cover the Dutch oven with its lid. Braise in the preheated oven for 1 hour and 15 minutes. Remove the pot from the oven, check for tenderness with a fork, and continue braising for an additional 1 to 1 ½ hours, or until the roast is easily pierced and falls apart.

• Thicken Gravy (Stovetop): Remove the cooked chuck roast from the Dutch oven and transfer it to a plate. Cover it loosely with foil to keep it warm. In a small bowl or mason jar, whisk together 2 tablespoons of cornstarch with the ⅓ cup of water until smooth. Place the Dutch oven back on the stovetop over medium-high heat until the liquid reaches a simmer. Slowly whisk in the cornstarch slurry, stirring constantly. Let the gravy regain a simmer and cook for 1-2 minutes until thickened. If it’s still too thin, mix the remaining tablespoon of cornstarch with 2 tablespoons of water, add to the pot, and cook for another 1-2 minutes, stirring.

Serve: Shred or slice the beef and return it to the thickened gravy in the Dutch oven.

Pro Tips for Perfect French Onion Pot Roast

Achieving the best French Onion Pot Roast is simple with a few key tricks. Follow these tips for a truly delicious result.

• Season Generously: Don’t be shy with salt and pepper on the chuck roast. This builds deep flavor from the start.
• Hot Pan for Searing: Ensure your skillet or Dutch oven is hot before adding the meat. A good sear develops a rich, crusty exterior.
• Oil with Butter: Using a splash of oil alongside butter prevents the butter from burning during searing, giving you golden-brown deliciousness.
• Don’t Move Meat While Searing: Allow the beef to develop a deep brown crust before flipping. Resist the urge to peek or move it too early.
• Allow Adequate Cooking Time: Patience is key for fork-tender beef. Don’t rush the slow cooking or braising process.
• Adjust Gravy Thickness: You can always add more cornstarch slurry (mixed with water) if you prefer a thicker gravy.
• Prep Ahead: You can sear the meat and sauté onions the night before. Store them separately in the fridge, then combine when you’re ready to cook.

Serving Suggestions

This hearty French Onion Pot Roast pairs wonderfully with a variety of sides.

• Mashed Potatoes: Creamy mashed potatoes are the ultimate classic accompaniment, perfect for soaking up all that rich gravy.
• Egg Noodles: Toss hot, buttered egg noodles with the pot roast and gravy for a comforting meal.
• Crusty Bread: Serve with a warm, crusty baguette for dipping into the delicious sauce. Consider topping slices with melted Gruyère or provolone cheese for a true French onion experience.
• Roasted Vegetables: Complement the richness with simple roasted carrots, green beans, or asparagus.

Storage & Reheating

Enjoying your delicious French Onion Pot Roast for days to come is easy.

• Store Leftovers: Transfer any leftover pot roast and gravy to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days.
• Freeze for Longer Storage: For extended enjoyment, freeze the pot roast in an airtight, freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Reheat: Reheat individual portions in the microwave until warmed through. For larger amounts, gently warm the pot roast in a pot on the stovetop over medium-low heat or in a slow cooker on the “warm” setting.

Variations

Customize your French Onion Pot Roast to suit your taste or what you have on hand.

• Add Vegetables: Incorporate chopped carrots, celery, or sliced mushrooms into the slow cooker or Dutch oven during the last few hours of cooking.
• Introduce Red Wine: For a deeper, more complex flavor, substitute half a cup of the beef broth with dry red wine, like a Cabernet Sauvignon or Merlot.
• Top with Cheese: Before serving, spoon the pot roast into oven-safe bowls, top generously with shredded Gruyère or provolone cheese, and broil until bubbly and golden.

Ingredients

  

Main Ingredients

• 2 pound chuck roast see notes for larger
• 2 tablespoons butter
• a splash oil
• 3 cloves minced garlic
• 2 large onions thinly sliced
• 2 cups beef broth
• 1 tablespoon Worcestershire sauce
• 1 tablespoon apple cider vinegar
• 0.5 teaspoon onion powder
• 0.5 teaspoon dried thyme
• 1 bay leaf
• 0.125 teaspoon celery seeds crushed between fingers
• 1 tablespoon sugar
• 2-3 tablespoons cornstarch
• 1/3 cup water

Instructions

 

Preparation & Searing

• Pat dry the chuck roast, season generously with salt and pepper, then sear on all sides for 2-3 minutes per side in a large skillet or Dutch oven with butter and oil until browned; remove the roast to a plate.
• Optionally, add a little more oil to the pan and sauté the thinly sliced onions for 3-4 minutes until they begin to soften.

Slow Cooker Method

• For the slow cooker, layer half the onions, followed by garlic, beef broth, Worcestershire, apple cider vinegar, onion powder, thyme, bay leaf, celery seeds, sugar, and the seared chuck roast, then top with the remaining onions. Cook on low for 6-8 hours until fall-apart tender.
• Remove the meat and keep it warm. Whisk 2 tablespoons of cornstarch with water and add to the slow cooker; stir and cook for 5-7 minutes until thickened. If needed, dissolve the remaining tablespoon of cornstarch in more water and cook for an additional 5 minutes.

Oven Method

• Preheat the oven to 275ºF. After sautéing onions (step 2), return the chuck roast to the Dutch oven, add garlic, beef broth (ensuring the roast is half submerged), Worcestershire, apple cider vinegar, onion powder, thyme, bay leaf, celery seeds, and sugar; stir to combine. Cover and braise in the oven for 1 hour 15 minutes, then continue for another 1 to 1 ½ hours until fork-tender.
• Remove the meat and keep it warm. Combine 2 tablespoons of cornstarch with water, then heat the Dutch oven on the stove over medium-high heat until the liquid simmers. Stir in the cornstarch mixture and let the gravy simmer until thickened. If needed, dissolve the remaining tablespoon of cornstarch in more water and cook for an additional 1-2 minutes.

Notes

For a larger chuck roast, cooking times may need to be adjusted. The slow cooker method yields a fall-apart tender roast in about 8 hours. Adjust cornstarch as needed for desired gravy thickness.
