    This ground beef zucchini rice casserole is a delicious stovetop one-pot recipe made with ground beef, sliced squash, garlicky onion tomato base, and rice.

    mahshi kousa casserole

    This recipe is inspired by a famous Lebanese stuffed squash recipe called mahshi kousa. Instead of coring the squash and stuffing it with rice and minced meat (like mahshi kousa), this recipe cooks everything together in one pot. This well-balanced stovetop rice dish has vegetables, protein, rice, and tons of flavor.

    Ingredient Notes

    mahshi sliced kousa ingredients
    • Minced ground beef: I prefer semi-lean ground beef for this recipe (85% to 90% lean). Ground lamb is a suitable alternative.
    • Rice: Any type of rice will do for this recipe, however, I prefer to use medium-grain rice like Jasmine rice.
    • Lebanese seven spices or allspice: Lebanese seven spices is a mixture of seven spices mixed together (black pepper, white pepper, allspice, ground clove, nutmeg, cumin, and cinnamon). It's commonly used in Lebanese and Middle Eastern cooking (chicken shawarma, kibbeh, etc). You can find it on Amazon, in a Middle Eastern grocery store, or make Lebanese seven spice at home yourself. If you don't have any on hand, substitute ground allspice or ground cinnamon.
    different types of squash suitable to make mahshi sliced kousa

    Calabaza Squash (Kousa): Kousa means squash in Arabic, but it means a particular type of squash. Kousa squash is the same as calabacitas squash (I've also seen it called calabaza squash or Mexican squash). It's small in size with yellow and green coloring. If you can't find this particular type of squash at your grocery store, you can use two substitutes: large green zucchini or baby green zucchini.

    How To Make Beef Zucchini Rice

    sliced kousa and chopped onions in a bowl

    Chop the onions and garlic. Slice the ends off of the squash. Chop the squash into circles.

    add some olive oil to a nonstick pot

    In a nonstick pot, add the olive oil on high heat.

    add the chopped onions and garlic

    Add the chopped onions and garlic to the olive oil.

    sautee the onions and garlic until browned

    Caramelize the onions and garlic on medium-high heat for about 3 to 5 minutes.

    add the ground beef to the caramelized onions

    Add the minced meat (ground beef or ground lamb).

    cook the ground beef until browned

    Brown the beef and break up the clumps. Add the salt, pepper, and Lebanese 7 spice to the ground meat. Mix well.

    add the fresh sliced calabaza squash

    Add the sliced squash.

    add the diced tomatoes and tomato paste to the pot

    Then, add the canned diced tomatoes, tomato paste, and water.

    add water to the mahshi sliced kousa

    Mix everything together well.

    simmer the mahshi sliced kousa on high covered

    Cook on medium-high heat covered with a lid for about 25 minutes or until the squash starts to tear apart.

    add long grain rice to the mahshi sliced kousa pot

    Add the rice.

    add another cup of water to the mashshi kousa

    Add an additional cup of water and mix. Turn the stovetop down to low heat.

    cover the mahshi cousa pot with a lid

    Cover the pot and cook for about 30 minutes until the rice is tender.

    Check halfway through and stir. Serve with some lemon and cucumber mint yogurt.

    Tips and Tricks

    The two main tips for this squash and rice casserole are the stovetop setting and the amount of liquid in the pot. Every stove and pot is different, elevations play a factor, and even the type of rice used can affect things. Therefore, make sure throughout this recipe that there is enough liquid in the pot and that the bottom isn't burning.

    I generally stir the squash and rice casserole every 10 to 15 minutes, especially the first two times I made it myself. It can be more hands-off after you have made it a few times.

    Variations and Substitutions

    • Substitute green zucchini for calabaza squash. If you can't find calabaza squash, green zucchini comes in a close second.
    • Use an extra can of diced tomatoes in lieu of tomato paste.
    • Substitute ground lamb for ground beef.

    This one-pot ground beef zucchini rice casserole has minced meat, spices, onions, garlic, tomatoes, squash, and rice.

    Ingredients
     
    US Customary - Metric

    • 5 cups sliced squash Calabaza, calabacitas, or Mexican squash** see note 1
    • 2 cups chopped onions
    • 8 garlic cloves
    • 1 lb minced ground beef or ground lamb
    • 1 cup long-grain rice
    • 14.5 ounces can of diced tomatoes
    • 6 ounces can tomato paste
    • 1 tablespoon Lebanese 7 spices or ½ tablespoon cinnamon
    • 5 cups water or chicken broth
    • salt and pepper to taste

    Instructions

    • Chop the garlic and onions to the same size. Slice the ends off of the squash. Slice the squash into thin circles.
    • In a nonstick large pot on high heat, add the olive oil. Once it starts to heat up, add the chopped onions and garlic. Sautee until starting to brown.
    • Add the minced meat to the sauteed onions. Break apart any clumps and cook until browned (about 3 to 4 minutes). Add the ground 7 spice, salt, and pepper. 
    • Turn the heat down slightly to medium-high heat. Add the sliced squash, canned diced tomatoes, canned tomato paste, and the water. Mix everything together. Cover and simmer on medium-high heat for about 25 minutes or until the kousa squash starts to break apart.
    • Add the rice. Mix well. Cover and cook on very low heat for 30 minutes or until the rice is tender. Mix at the halfway mark again so the rice doesn't stick to the bottom of the pot. Add water if needed (maybe ½ a cup or cup).

      This is a great way to use up zucchini from the garden. We always have way too much and I'm never sure what to do with it all!
