Step by Step Instructions

Step 1: Prepare the onions

Heat olive oil and butter in a large skillet or directly in the slow cooker insert if your appliance allows. Add the sliced onions and cook over medium heat until they become deep golden brown and caramelized. This may take 15 to 20 minutes, but the patience pays off as the onions develop the signature French onion flavor that defines this dish. Stir occasionally to ensure even cooking and prevent burning.

Step 2: Sear the roast

While the onions caramelize, season the beef roast generously with salt and black pepper. In a separate skillet, sear the roast on all sides over medium-high heat until browned. This step locks in juices and adds additional flavor through the Maillard reaction, which enhances the complexity of the final dish.

Step 3: Combine ingredients in the pot

Transfer the seared roast to the slow cooker or oven-proof pot. Layer the caramelized onions on top and around the roast. Add minced garlic, beef broth, dry white wine if using, thyme, rosemary, and Worcestershire sauce. Stir gently to combine, ensuring the roast is partially submerged in liquid while leaving some onion on top for flavor infusion.

Step 4: Slow cook the roast

For slow cooker method, cover and cook on low for 4 to 6 hours, or until the meat is fork-tender. For oven method, cover with a lid or foil and bake at 325°F for 3 to 4 hours. The roast should easily pull apart with a fork, and the onions should create a rich, flavorful sauce. Check occasionally to ensure liquid levels are sufficient; add additional broth if necessary.

Step 5: Optional: thicken the sauce

Once the roast is done, remove it from the pot and let it rest for 10 to 15 minutes.

This step transforms the natural juices into a luscious gravy perfect for serving over mashed potatoes or roasted vegetables.

  • French Onion Pot Roast with Red Wine
