Slow Cooker French Onion Beef

ByDavid Loa

Looking for a fuss-free weeknight dinner? These Slow Cooker French Onion Beef Tips are incredibly tender, packed with rich caramelized onion flavor, and require minimal prep!

The Story Behind the Recipe

Let me be real with you—weeknights in my house get chaotic. Between work, errands, and trying to keep everything somewhat organized, standing over a hot stove for an hour is usually the last thing I want to do. That’s exactly how this recipe became a weekly staple for us.

I usually throw these beef tips into the slow cooker in the morning before heading out, and honestly, coming home to the savory, rich aroma of French onion gravy simmering away is the absolute highlight of my day. It’s like having a gourmet meal waiting for you, but it only took about 10 minutes of active prep! The beef gets so tender it practically melts in your mouth, and those onions? Absolute perfection.

Ingredients List

  • 2 lbs beef chuck roast, cut into 1.5-inch cubes (stew meat works too!)

  • 2 large yellow onions, sliced thick

  • 1 packet (1 oz) French onion soup mix

  • 1 ½ cups beef broth (low sodium preferred)

  • 1 tbsp Worcestershire sauce

  • 2 cloves garlic, minced

  • 2 tbsp unsalted butter, cut into small pieces

  • For the slurry: 2 tbsp cornstarch + 2 tbsp cold water

Step-by-Step Method

  1. Prep the Slow Cooker: Spray the inside of your slow cooker with a little non-stick spray to make cleanup a breeze.

  2. Layer it Up: Add the cubed beef to the bottom of the slow cooker. Top it with the thick slices of yellow onion.

  3. Mix the Gravy: In a small bowl, whisk together the beef broth, French onion soup mix, Worcestershire sauce, and minced garlic until combined.

  4. Pour and Cook: Pour the broth mixture evenly over the beef and onions. Scatter the small pieces of butter on top. Cover and cook on LOW for 7-8 hours (or on HIGH for 4-5 hours), until the beef is fork-tender.

  5. Thicken the Sauce: About 30 minutes before serving, whisk the cornstarch and cold water together in a small cup to make a slurry. Stir the slurry into the slow cooker. Cover and cook on HIGH for another 20-30 minutes until the gravy is thick and glossy.

Cooking Tips

  • Don’t slice the onions too thin! I honestly recommend keeping them somewhat thick so they don’t completely disintegrate during the long cooking time.

  • Sear for extra flavor: If you have an extra 10 minutes in the morning, searing the beef cubes in a hot skillet before adding them to the slow cooker adds a phenomenal depth of flavor. But if you’re in a rush, just tossing them in raw works wonders too!

Serving Suggestions

I usually serve these saucy beef tips over a mountain of creamy mashed potatoes—it is the ultimate comfort food combo. They are also fantastic over wide egg noodles, steamed white rice, or just with a big hunk of crusty French bread to mop up every last drop of that incredible onion gravy.

5 FAQs

1. Can I use pre-cut stew meat instead of chuck roast? Absolutely! I often buy pre-cut beef stew meat when I’m short on time. Chuck roast yields the absolute most tender results, but stew meat works perfectly fine and is super convenient.

2. Do I have to use the cornstarch slurry? Not at all. If you prefer a thinner broth-like sauce (similar to French onion soup), you can skip the slurry. I usually add it because we love a thick, rich gravy to coat our mashed potatoes.

3. Can I cook this on HIGH if I’m in a hurry? Yes! You can cook it on HIGH for 4 to 5 hours. However, for the absolute most tender, melt-in-your-mouth beef, cooking it on LOW for 7-8 hours is always my recommendation.

4. How long do leftovers last? Store any leftover beef tips and gravy in an airtight container in the fridge for up to 4 days. Honestly, I think the flavor gets even better the next day as everything marinates!

5. Can I freeze this recipe? You sure can. Let it cool completely, then transfer to a freezer-safe container or bag. It will keep well in the freezer for up to 3 months. Just thaw in the fridge overnight and reheat gently on the stove or in the microwave.
