How to Make French Onion Pot Roast

Step 1: Caramelize the Onions

Melt butter with a splash of olive oil in a Dutch oven. Add your onions and cook low and slow until golden and sweet. This takes time—about 30-40 minutes—but it’s worth every second.

Step 2: Sear the Roast

While your onions work their magic, season your chuck roast with salt and pepper. In a hot pan (or remove onions temporarily from the Dutch oven), sear the roast on all sides until beautifully browned.

Step 3: Build the Braise

Add the onions back in (if removed), then toss in garlic, thyme, bay leaves, beef broth, and Worcestershire. Bring it to a simmer.

Step 4: Slow Cook to Perfection

Cover and pop the Dutch oven into a preheated oven at 325°F. Let it do its thing for 3 to 3.5 hours, until the roast is fork-tender and falling apart. For an Instant Pot Pressure Cooker version, cook on high pressure for about 60-70 minutes.

Step 5: Cheese It Up

Sprinkle shredded Gruyère or Swiss on top and broil until bubbly and golden. Hello, ooey-gooey heaven!

Pro Tips

  • Use a mandoline for super even onion slices.
  • Deglaze the pan with a splash of white wine or brandy after searing the meat for added depth.
  • Let the roast rest before shredding so it stays juicy.

Flavor Variations

  • Add mushrooms with the onions for an earthy twist.
  • Swap Gruyère for provolone or mozzarella if that’s what you have.
  • A splash of balsamic vinegar at the end adds a little zing.
