This French Dip Sandwich is amazing! It comes together with simple ingredients in the crockpot and is perfect for a busy weeknight dinner.
With three kids in the busiest years of school, our family is always on the go. But we really try to make family dinner a priority. It’s the time that brings us all together to connect, and of course that is better when it’s around a good meal. Two things really help make weeknight dinners happen, the first is planning and the second is our slow cooker.
French Dip Sandwiches are the perfect slow cooker dinner. These are easy to prepare, made with simple ingredients, and when you come home after a long day you have the best dinner waiting for you.
How to Make French Dip Sandwiches
This is a brief overview of how to make these slow cooker sandwiches. For the full recipe with all of the measurements, see the recipe card at the bottom of the post.
- Sear the meat. Heat oil in a skillet until it is smoking. Season the meat with salt and pepper and sear it on all sides (keep in mind the meat has six sides, not two). Read more on this below.
- Combine the ingredients in the slow cooker. While the meat is searing, combine the the French onion soup, beef broth, Worcestershire sauce, onion flakes, garlic, bay leaves, and oregano in the slow cooker.
- Slow cook the meat. Add the seared meat, and cook on low for six to eight hours. Read below on why I’m adamant about cooking on low.
- Slice the meat. After the meat is done cooking, let it rest for 10 minutes outside of the slow cooker. You can slice it very thin with a sharp knife, or you can shred it.
- Serve the sandwiches. Add the meat, a little of the au jus sauce to rolls and enjoy. Please see below for the option of adding cheese.
Adding Cheese to French Dip Sandwiches
These are amazing on their own, and my family also loves them with some cheese. A great way to add the cheese is the following steps. It also deepens the flavor without adding the cheese; though I know you will love these without the extra steps.
- After slicing the meat, place half of it in a skillet.
- Add a ladle-full of the au jus sauce to the skillet. Bring the sauce to a simmer.
- Turn off the heat and top with the cheese. Cover and allow it to melt.
- Add the meat and cheese to the rolls and serve.
Searing Meat Before Slow Cooking
I have a lot of slow cooker recipes where the first step is searing the meat all over. I inevitably get asked if this is truly necessary. The simple answer is: No, but do it anyway.
The point of searing meat before putting it in a slow cooker, or even cooking it on low even in the oven like in my Pot Roast, isn’t about cooking. The point isn’t to begin the cooking process, it is because searing the meat adds flavor to the meat. If you skip this step and just pop it in the slow cooker, you are going to miss out on that flavor.
Slow Cooking Meat on Low
While I have a lot of slow cooker recipes that give you a cooking range for low and for high, I’m pretty insistent with this recipe that you should stick to cooking on low.
Certain cuts of meat, like the rump roast, do best when you cook them low and slow. It’s that method of cooking that makes them nice and tender. The high setting for slow cookers is a high enough temperature, that you are loosing that low and slow method. While you can cook these on high, I think that you will be disappointed with the texture of the meat if you cook it this way.
Traditionally, French Dip Sandwiches are made with Rump Roast. This is a great piece of meat to cook with because it is usually really affordable. That being said, it is a very lean cut of meat, so it really needs to be cooked low and slow. This is another reason to stick to cooking on low.
In addition to cooking this cut on low, another key to this cut of meat is cutting it against the grain. When you remove the meat from the slow cooker, after letting it rest look at the lines in the meat and cut against them (as pictured above).
Slow Cooker Recommendation
If you are new to slow cooking, you are going to love all of the easy dinner recipes that you can come home to. You can find all of my crockpot dinners here: Crockpot Dinner Recipes.
I love this slow cooker so much that I own several of them. This great crockpot holds up over the years, is 6 quarts, and cooks things perfectly.
Storing Leftovers and Freezing
Leftovers can be stored in the refrigerator for four to five days. I prefer to store the meat in the liquid that it was cooked in.
These work great for freezing. I like to add the meat back to the liquid and store in a sealable container with an inch of room at the top for the liquid to expand. Store in the freezer for up to three months. When ready to eat, remove the container and thaw in the refrigerator overnight.
What to Serve with French Dip Sandwiches
