Recipe Notes

  • The recipe called for 1/2 cup of liquid to be taken from the crock pot after cooking, I had a hard time getting 1/2 cup. So if you have the same thing happen to you, feel free to use a little bit of water to make sure that your stuffing is nice and coated and becomes fluffy after cooking.
  • This may seem like a weird combination of flavors, but I beg of you…give it a try! You’re gonna love it!

    I was unable to find canned onion soup – would it be best to substitute with Beef Broth, or could I use an onion soup packet + water?

      Oh no Adrea! I haven’t tried this with the substitutions you are asking about. If I did, I would probably use the onion soup packet and beef broth. If you give it a try, let me know how it turns out!

    • Crock Pot French Onion Beef Casserole - Recipes That Crock! (13)Adrea says

      I ended up using beef broth and 1/2 a packet of dry onion soup mix. Tasted great, I’m sure it was close to the canned onion soup.
      There was quite a bit of liquid after I removed the amount to add to the stuffing. I added some cornstarch to thicken it and make a gravy. Worked well!

    Absolutely amazing flavor. However i did substitute a liquid French onion soup. The 3 cups of water from that gave the meat plenty of water to cook in and use for the stuffing.

      Hi Tina-
      We haven’t tried it in the Instant Pot yet, so we can’t really say until we try it. If you do, we’d love to know how it went!

    • Crock Pot French Onion Beef Casserole - Recipes That Crock! (23)Jordan says

      did you ever figure out how to cook this in the pressure cooker/ instant pot ?

  5. Crock Pot French Onion Beef Casserole - Recipes That Crock! (24)Pat Cody says

    If I divide one pound of meat into 6 pieces, it’s still 1/6th of a pound and there is no way this is going to make 6 servings in my house. It sounds delicious but I’m thinking 3-4 servings at most, more like 2 at my house. 🙂

      Hi Pat!

      I think the recipe said 4-6 servings because of all of the other things in the recipe. Even with Michael eating large portions, we had enough for two meals, but portions are always up for interpretation. Hope you guys enjoy this as much as we did!

    Hi! What kind of herb stuffing mix are you talking about…the instant kind with poultry seasoning?

      Hi Debby!

      Yes, Stove Top (or the generic version) stuffing is what I am talking about. The kind the recipe said to use was the herb flavored. The kind I found was savory herb. I haven’t tried it with a different kind, but my guess is that you could use the chicken flavored if you can’t find the herb flavored. Enjoy!
