    One Pot Creamy Rigatoni with Beef and Diced Tomatoes Recipe

    Ingredients for One Pot Rigatoni 

    This creamy, easy to make pasta dish calls for only basic ingredients (may of which you can substitute if you don’t have them on hand). The end result is a creamy pasta loaded with beef, tomatoes, peppers and onions that is loaded with flavor. For this recipe you will need:

    • olive oil
    • bell peppers- any color will work. We used red and orange but green or yellow are great too! 
    • sweet onion
    • garlic
    • ground beef- we used lean ground beef but any ground beef will work. 
    • canned diced tomatoes
    • rigatoni pasta- if you don’t have rigatoni on hand any pasta shapes will work for this recipe. Gluten-free pasta can also be used for this recipe.
    • beef broth- vegetable or chicken broth will also work. 
    • milk- any kind of milk from full fat to skim milk or low-fat milk can be used; to make this recipe dairy-free use your favorite plant-based milk 
    • italian seasoning 
    • salt
    • black pepper

    How to Make One Pot Rigatoni 

    Step One: Prepare vegetables and heat pot

    To start, chop the peppers, onion and garlic and set aside. Next, take a big pot and place on the stove. Turn heat to medium and let the pot heat up. Once hot, add the olive oil.

    Step Two: Saute vegetables

    Then, add the chopped peppers, onions and garlic. Saute the vegetables for 5-8 minutes or until they start to get tender. 

    Step Three: Cook beef

    Next, add the ground beef and cook until brown. Break up the ground beef as it cooks into smaller pieces.

    Step Four: Add remaining ingredients

    Once beef is cooked add all remaining ingredients: canned diced tomatoes, uncooked rigatoni pasta, beef broth, milk, italian seasoning, salt and pepper. Turn up the heat to medium-high heat and bring the liquid to a boil. Once boiling reduce to a simmer and cover the pot. 

    Step Five: Cook until pasta is al dente

    Stir frequently and cook until all liquid is absorbed and pasta is al dente. If liquid is absorbed and pasta is not cooked to your liking add a little more broth a half cup at at time. Serve immediately. Top with parmesan cheese if desired.

    Recipe Modifications

    Can I make this pasta with a different protein?

    Of course, this pasta recipe can be made with ground chicken, ground pork or ground italian sausage. Simply follow the same directions and swap the protein. 

    Can I make this recipe gluten or dairy free?

    Yes, to make this recipe gluten free use a gluten free pasta in place of the rigatoni. Do not worry about using the same shape since gluten free pasta varieties do not come in every shape. To make this recipe dairy free use your preferred plant-based milk in place of the milk in the recipe. 

    Can I make this recipe spicy?

    Absolutely! Try adding a little bit of red pepper flakes to make a spicy rigatoni dish. 

    Are there any other modifications I can make to this recipe?

    Of course, once the pasta has cooked there are lots of options for this recipe. You could try adding some marinara sauce, bolognese sauce or alfredo sauce, stir in some fresh spinach and let it cook quickly, stir in a little cream cheese to make it even creamier!
