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!

  1. […] Slow Cooker Stuffing. It is basically the only way to do stuffing in my book. Then when I had Crock Pot French Onion Casserole, I loved the cheese with the stuffing. So I couldn’t wait to give this a try and share it […]

FAQs

How long can you leave a casserole in a slow cooker? ›

Most appliances will automatically shut off after 20 or so hours on this setting, but you shouldn't leave food in a slow cooker for an extended length of time. The general rule of thumb is that 2-4 hours is the maximum length of time you can leave food in a slow cooker on warm.

Does cooking meat longer in a crock pot make it more tender? ›

Your meat will be juicier and more tender

The longer cooking time and the low heat complement each other perfectly. As a result, even though the meat is cooked for far longer, it doesn't dry out because the temperature is low. As a result, this is the best way to retain all the natural juices of the meat.

Should you cook onions before putting in crockpot? ›

It can be nice to cook the onions beforehand, as the flavour is different to when you put them in raw, but experiment both ways as you may find you prefer one. It can also be good to brown meat to give it some colour, but again, this is not essential.

How long does it take onions to get soft in crock pot? ›

If you're around while the onions are cooking, stir them occasionally — this will help them cook more evenly, but isn't strictly necessary. After 10 hours, the onions will be golden-brown and soft, and they will have released a lot of liquid.

Is 4 hours on high the same as 8 hours on low? ›

Low: 7-8 hours to reach the simmer point. High: 3-4 hours to reach the simmer point.

Is it safe to leave a crockpot on low overnight? ›

Can I leave a slow cooker on for 12 hours? ›

People do this all the time, but many aren't truly confident that it's 100 percent safe — I, for one, am one of those people. So I did a little digging to get the hard facts. The truth is, yes, leaving the slow cooker on and going about your day is safe, as long as you are using the appliance properly.

Can you keep a casserole warm in a slow cooker? ›

Slow Cooker or Chafing Dishes

Can something be in the slow cooker too long? ›

How long can I leave chicken in the crockpot on low? ›

Cook bone-in chicken breasts in slow cooker on LOW for 2-3 hours or HIGH for 1-2 hours. Bone-in chicken is less likely to dry out than boneless, so you have the flexibility to cook the chicken on high. Based on medium bone-in chicken breast with a weight of 11 ounces.
