Ingredients You’ll Need

1 packet (1 oz) beefy onion soup mix
1 teaspoon dried thyme
1/2 teaspoon dried rosemary
2 cans (10.5 oz each) condensed French onion soup, divided
2-3 lb chuck roast
1 teaspoon kosher salt
1 teaspoon black pepper
2 tablespoons vegetable oil
1/2 cup unsalted butter, sliced
1/4 cup water
2 tablespoons cornstarch
Chopped parsley (optional, for garnish)

Step-by-Step Instructions

1. Prepare the Ingredients

In a bowl, mix together the onion, garlic, soup mix, thyme, and rosemary until well combined.

2. Set Up the Slow Cooker

Spray the inside of your 8-quart slow cooker with cooking spray. Add half of the onion mixture to the bottom and pour one can of condensed French onion soup over it.

3. Season and Sear the Roast

Pat the chuck roast dry with paper towels and season all over with salt and pepper.
Heat a large skillet over medium-high heat and add the vegetable oil.
Sear the roast for about 5 minutes per side until golden brown.

4. Assemble and Cook

Place the seared roast into the slow cooker.
Top with the remaining onions and the second can of French onion soup.
Dot with butter slices, cover, and cook on LOW for 6-8 hours or HIGH for 4-6 hours.

5. Make the Gravy

Once the roast is done, remove it from the slow cooker and set it aside.
Pour the remaining liquid into a skillet over medium heat.
In a small bowl, mix water and cornstarch to create a slurry.
Slowly whisk the slurry into the simmering liquid and continue to cook until the gravy thickens.

6. Serve and Enjoy

Return the shredded roast to the slow cooker and mix with the gravy.
Garnish with chopped parsley and serve over mashed potatoes, noodles, or rice.

FAQs

Can I use a different cut of meat for this recipe?

Yes! While chuck roast is best due to its marbling, you can substitute with brisket, bottom round, or beef shoulder roast. Just keep in mind that leaner cuts might be less juicy.

Do I have to sear the roast before putting it in the slow cooker?

Searing isn’t mandatory, but it adds a rich depth of flavor. If you’re short on time, you can skip this step, but your roast might not be as flavorful.

Can I make this without a slow cooker?

Absolutely! Cook it in a Dutch oven at 300°F (150°C) for 3-4 hours until the meat is tender.

How can I make this dish keto-friendly?

To make this low-carb, skip the cornstarch and use xanthan gum as a thickener. Also, ensure your onion soup mix doesn’t contain added sugars or starches.

Can I prepare this meal ahead of time?

Yes! You can assemble everything the night before, store it in the fridge, and pop it into the slow cooker the next morning.

What are the best side dishes to serve with this pot roast?

This French Onion Pot Roast pairs well with:
. Mashed potatoes or buttery egg noodles
. Roasted vegetables (carrots, green beans, Brussels sprouts)
. Crusty bread to soak up the delicious gravy

How to Store & Reheat Leftovers

Refrigerate: Store in an airtight container for up to 3 days.
Freeze: Keeps well for up to 3 months. Thaw overnight in the fridge before reheating.
Reheat: Use the microwave, stovetop, or slow cooker. If the gravy is too thick, add a splash of beef stock or water.
