Slow Cooker Pot Roast

The classic roast of meat and meat sauce is made even easier in a slow cooker!
Roast beef is a classic that is always welcome and super easy to make, especially in a slow cooker. Just throw the meat into a crockpot and simmer it all day long. I like to season the meat with salt and pepper along with onions, garlic, rosemary, and thyme and it is easy to change the seasonings to taste. If you want you can brown the meat in a pan (over medium-high heat) and sauté the onions and garlic before adding them to the slow stove to add a little more flavor, but just throwing all this away works too! The sauce is the key and it only takes a few minutes to make it in a pan on the stove after the roast is done. I like to serve the roast and sauce over the mashed potatoes (or cauliflower puree) along with a vegetable for a full meal.

This is a pantry meal if you have a roast in the freezer and onions in the pantry along with a frozen or canned vegetable.
