French Onion Garlic Butter Pot Roast: One-Pot Comfort Tips, FAQ & printable recipe

Tips for success

For the most flavorful gravy, use a good-quality beef consommé. It's richer than broth and has a deeper, more concentrated taste. If you only have beef broth, add a teaspoon of Worcestershire sauce or a splash of soy sauce to boost the umami.

You can also stir in a tablespoon of tomato paste for extra depth. Don't skip the butter—it's what makes the sauce silky and luxurious.

To make the compound butter, let 4 tablespoons of unsalted butter soften, then mix in 2 minced garlic cloves and 1 teaspoon of dried herbs (thyme, rosemary, or parsley). Roll it into a log using plastic wrap and chill until firm, then slice into medallions.

If you're in a hurry, you can simply place the butter in small pats on top of the roast—it will melt just the same. The butter is also delicious on steaks or roasted vegetables.

Variations

• Mushroom & Thyme: Add 8 oz sliced cremini mushrooms along with the onions. Use 2 cups beef broth instead of consommé and add 1 teaspoon dried thyme. The mushrooms add an earthy depth that pairs beautifully with the garlic butter.
• Spicy Kick: Add 1-2 sliced jalapeños or a teaspoon of red pepper flakes with the onions. Use a spicy compound butter, or mix a pinch of cayenne into the regular butter. Serve with pickled onions for extra tang.
• Red Wine Braise: Replace 1/2 cup of the consommé with dry red wine, such as Merlot or Cabernet Sauvignon. Add a sprig of fresh rosemary and a bay leaf. The wine adds a rich, fruity complexity to the gravy.
• Herb-Crusted: Before placing the roast in the slow cooker, rub it with 2 tablespoons of dried herbs (thyme, oregano, rosemary) and a teaspoon of salt and pepper. The herbs form a flavorful crust as the roast braises.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat on the stovetop or microwave, adding a splash of broth if needed.

Freezer

Freeze the beef and gravy in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheat

Reheat gently on the stovetop over low heat, stirring occasionally, until warmed through. Add a little beef broth or water if the gravy is too thick.

Store leftover beef and gravy in an airtight container in the refrigerator for up to 4 days. The flavors will continue to meld, making it even more delicious the next day.

Reheat gently on the stovetop or in the microwave, adding a splash of beef broth if the gravy has thickened too much. The beef can also be frozen for up to 3 months; thaw overnight in the refrigerator before reheating.

This recipe is perfect for meal prep. You can assemble the entire dish—roast, onions, consommé, and butter—in the slow cooker insert the night before, cover, and refrigerate. In the morning, simply place the insert in the slow cooker and cook as directed.

The compound butter can also be made ahead and stored in the refrigerator for up to a week or frozen for up to 3 months. Cooked leftovers freeze beautifully, so consider making a double batch.

Serving ideas

Serve the French onion garlic butter roast over a bed of warm buttered egg noodles. The noodles are the perfect vehicle for the rich, savory gravy. You can also serve it over mashed potatoes, polenta, or crusty bread to soak up every drop. A simple green salad with a light vinaigrette makes a refreshing contrast to the rich beef.

For a complete meal, add a side of steamed green beans or roasted carrots. The sweetness of the vegetables complements the savory beef and onions. If you have leftover gravy, it's wonderful drizzled over the noodles or used as a dipping sauce for crusty bread. Garnish with fresh chopped parsley or thyme for a pop of color, if desired.

French Onion Garlic Butter Pot Roast: One-Pot Comfort

Prep 15 minCook 8 hRest 10 minTotal 8 h 25 minServes 6

Ingredients

• 3 1/2 lb beef bottom round roast
• 2 large Vidalia onions, thinly sliced
• 2 cups beef consommé
• 4 tbsp garlic-herb compound butter (cowboy butter), cut into medallions
• 12 oz buttered egg noodles, for serving

Instructions

1. Place the beef bottom round roast in the center of a 6-quart slow cooker. Scatter the sliced Vidalia onions over and around the roast, then pour the beef consommé around the base, being careful not to rinse the onions off the meat.
2. Place the four medallions of garlic-herb compound butter directly on top of the roast. They will melt and baste the meat as it cooks.
3. Cover the slow cooker and cook on low for 8 to 10 hours, until the beef is fork-tender and easily shreds. The onions will caramelize and the consommé will reduce into a rich gravy. Let it rest for 3 minutes before slicing.
4. After 8 hours, insert an instant-read thermometer into the thickest part of the roast. It should read at least 145°F (63°C). Then, using two forks, test if the meat pulls apart easily. If not, continue cooking for another hour. Let it rest for 3 minutes before slicing.
5. Turn off the slow cooker and let the roast rest in the hot liquid for at least 10 minutes. This allows the juices to redistribute and the meat to become even more tender.
6. Transfer the roast to a cutting board. Using two forks, shred the beef into large chunks, discarding any large pieces of fat. Return the shredded beef to the slow cooker and stir into the onion gravy.
7. Spoon the buttered egg noodles onto a serving plate. Top with a generous portion of the shredded beef and ladle the onion gravy over everything. Serve hot.
