The slow cooker is one of our most favorite kitchen appliances. Although this sauce starts on the stovetop to develop and deepen the flavors, it finishes in the slow cooker and will make your home smell amazing! We love using a slow cooker to develop rich, complex flavors, without having to take up space on a burner for 8 hours. While we do suggest cooking this sauce on low in the slow cooker for 8 hours, there’s plenty of inactive time while it’s in the slow cooker so you can work on other things. We absolutely love this low carb and keto friendly ground lamb sauce.

Here’s What We Used For This Lamb and Mushroom Ragu (Slow Cooker):​

What Is a Ragu Sauce?

So, what makes a ragu a ragu you ask? It’s a bit of a broad definition, but technically it’s a rich, slow cooked sauce for pasta that is primarily made of meat! So naturally, this description fits our recipe. We added in mushrooms because, who doesn’t love mushrooms in their pasta sauces?! It makes for a great, savory and earthy flavor to accompany the meat and tomatoes.

What Cut of Lamb Do I Use and How Do I Prepare It?

Many recipes call for lamb shoulder. Lamb shoulder would most definitely be delicious in this recipe, but it is a more expensive cut of meat. We also find it a bit more difficult to find! We love using ground lamb and think it works perfectly in this recipe. Ground lamb is pretty easily accessible at many grocery stores, and we found ours at Aldi. No matter what cut of lamb you are using, you should definitely brown it in a skillet before adding it to the slow cooker. You could technically add the ground lamb to the slow cooker raw, but we promise, it will not taste as good or be nearly as tender. Browning the meat allows it to develop more flavor, and taste as you go. We like to add a lot of the salt at the stages where we brown the meat and caramelize the vegetables. It helps us control the salt levels and develop such nicer flavors in the dish.

What Type of Red Wine Should I Use?

For this recipe, you should pick a good quality red wine. That doesn’t mean you have to spend a fortune, but you do want something that tastes great. We opt for a drier variety, especially since we eat low carb. Cabernet Sauvignon, Pinot Noir, or Merlot would make good choices. They are on the drier side, but pack plenty of body and fruit flavor that will turn into such a rich sauce. You can also enjoy a glass with dinner when it’s all done! You don’t need to go crazy picking a wine. Something drinkable works. You definitely don’t need to spend more than $10-15 for a bottle.

Do I Have To Use a Slow Cooker?

While we do prepare our lamb and mushroom ragu in the slow cooker, you definitely don’t have to. We like to prepare ours in the slow cooker so we can keep our stovetop burners free, and go about our day without having to worry about the ragu sauce. This recipe is truly a perfect candidate for a slow cooker, after we brown the meat and cook the vegetables a little bit. Ragu sauce is meant to be cooked low and slow for hours, until a thick, rich sauce is achieved. If you do prefer to use a dutch oven, go for it! It would make sense, since we start this recipe on the stovetop. You will just want to cook this sauce for hours, at least 4, so it can get nice and tender. We cooked our lamb and mushroom ragu for 8 hours in the slow cooker so the meat became super tender and delicious.

How to Make This Lamb and Mushroom Ragu in the Slow Cooker:

Start by prepping your vegetables. We minced our onions, garlic, carrots, and celery really fine. Thinly slice your mushrooms. Set them aside. Preheat a cast iron skillet over medium heat. We will start the sauce in cast iron and then move it to the slow cooker for the best possible flavor.

In a hot skillet with olive oil, brown your ground lamb with salt and pepper. Once it’s cooked through, remove it from the skillet and add it to your slow cooker. Add the remaining olive oil, then add your onions, carrots, and celery with some salt. Cook until caramelized, about 7 minutes. Add in your tomato paste and cook until the color deepens slightly. Add in your mushrooms, with a pinch more of salt, then cook for 3-4 minutes until lightly softened. Now, stir in your minced garlic, smoked paprika, and red pepper flakes and cook until fragrant, about 30 seconds, then immediately remove from the heat.

Add your cooked vegetables to the slow cooker with the cooked lamb. Pour in your beef broth, and red wine. Add your herb bundle, and some bay leaves. Cover with the lid and let it cook for 8 hours! Stir every so often.

After cooking, remove the herbs and the bay leaves and discard. Taste, and adjust seasonings if necessary. Serve with pasta or pasta replacement of choice. Top with whatever you like. We love to top with ricotta, parmesan and some fresh basil.
