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!

FAQs

Does meat get more tender the longer you cook it in a slow cooker? ›

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.

What is the best meat to slow cook in a slow cooker? ›

Choose the right cut: Chuck roasts, short ribs, pork shoulders and lamb shanks (think fatty and tougher meats) become meltingly tender with the moist, low heat of a slow cooker. Leaner cuts like pork tenderloin tend to dry out. Likewise, dark meat chicken — thighs, drumsticks, etc.

What is the best beef for casserole? ›

Chuck, braising and stewing are all suitable for long slow cooking. Delia says…. My own favourite cut for braising, where I live in East Anglia is called chuck and blade steak. In other regions it can be called shoulder, which is exactly where it is.

What happens if you don't brown meat before a slow cooker? ›

"Browning, or caramelizing, meat before putting it into a slow cooker isn't 100 percent necessary, but it is well worth the effort for the most flavorful and full-bodied end result," he says. "The caramelized surface of the meat will lend rich flavor and color to the finished dish."

Why are my potatoes still hard in the crockpot? ›

Insufficient Liquid: If there wasn't enough liquid in the crockpot, it could have caused uneven cooking. Potatoes need to be fully submerged in liquid to cook evenly. Old Potatoes: Very old or stored potatoes can become starchy and may not soften as well during cooking. It's best to use fresh, firm potatoes.

Can you put raw beef in the slow cooker? ›

Certainly, foods will cook faster on high than on low. However, for all-day cooking or for less-tender cuts, you may want to use the low setting. It's safe to cook foods on low the entire time -- if you're leaving for work, for example, and preparation time is limited.

How to add more Flavour to beef casserole? ›

Add spices such as turmeric, coriander and cumin at the early stage of cooking, when you are frying onions and garlic, to enhance the taste of the beef stew. Fresh herbs like coriander and bay leaves also contribute a distinct flavour without making the dish too spicy for the younger members of the family.

Why is my beef casserole tough? ›

Two options really, either it is really a poor cut of beef, or more likely it hasn't been cooked for long enough. Usually 3 hours in the oven in a casserole dish at 180C/350F should make any cut of beef tender. You're not cooking it long enough l. A good sterw cooks and bubbles for hours.

Do you have to brown meat before making a casserole? ›

It's not necessary in every case. There's a couple slow cooker stew recipes I've used where I think they just boost the aromatics and soy sauce to make up for any lost flavor from the skipped maillard process. Browning meat adds flavor. There is very rarely a recipe where you wouldn't want it.

Can I use a jar sauce in a slow cooker? ›

Chicken Tikka Masala

Arrange in a single layer in the slow cooker. Add a 12- to 15-ounce jar tikka masala sauce, such as Maya Kaimal. Cook on LOW 2 to 3 hours or HIGH 1 to 2 hours.

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.
