Instructions

  1. Preheat and prep

    1. Preheat the oven to *375°F* and lightly coat a *9-by-13-inch baking dish* with a little olive oil. Finish the quick prep: dice the pepper and onion, slice the mushrooms, mince the garlic, and *rinse the red lentils*.

  2. Boil the pasta

    2. Bring a large pot of water to a boil. Cook the rigatoni *2 minutes less than package directions* until *very firm al dente*, then drain.

  3. Sauté the vegetables

    3. Meanwhile, heat the olive oil in a large skillet over medium-high heat. Add the onion, bell pepper, mushrooms, 1/2 teaspoon salt, and black pepper; cook for *6 to 8 minutes* until the vegetables are *softened and lightly browned*.

  4. Build the lentil-tomato sauce

    4. Stir in the garlic, oregano, and basil; cook for *30 seconds* until *fragrant*. Add the red lentils, crushed tomatoes, vegetable broth, and remaining 1/2 teaspoon salt.

  5. Simmer the sauce

    5. Bring the sauce to a simmer, then reduce the heat to medium-low. Cook for *18 to 20 minutes*, stirring often, until the lentils are *tender* and the sauce is still a little loose.

  6. Assemble the casserole

    6. Add the drained rigatoni to the prepared baking dish. Pour the lentil-tomato sauce over the pasta and *fold gently* until the rigatoni is *evenly coated*.

  7. Bake

    7. Cover the dish tightly with foil and bake for *15 minutes*. Uncover and bake for *10 minutes more* until the casserole is *bubbling* and the pasta is tender.

  8. Rest and serve

    8. Let the casserole rest for *5 minutes* before serving so the sauce can *settle and thicken*.
