Ingredients
12 ounces mushrooms, cleaned and chopped or sliced
1 tablespoon olive oil or neutral cooking oil
1 large onion, chopped
5 cloves garlic, minced
1 bell pepper (any color), seeded and cored, finely chopped
Salt, to taste
1 1/2 pounds lean ground beef (90:10 is good)
1 (28-ounce) can whole plum tomatoes in juice
3 tablespoons tomato paste
3/4 teaspoon dried oregano
1/4 teaspoon crushed red pepper flakes
Freshly ground black pepper
12 ounces (2 3/4 cups) uncooked elbow macaroni
8 ounces grated cheddar cheese (2 generous cups), divided
4 ounces grated Parmesan cheese (1 1/2 cups), divided
Method
- Preheat the oven to 350°F.
Grease a 9x13-inch baking dish; set aside.
- Cook the vegetables and beef:
Heat a large, deep skillet over medium-high heat. Add the mushrooms to the dry skillet. As they heat, the mushrooms will give off their moisture. Stir them occasionally until they are soft, slightly browned, and most of their liquid has evaporated, 5 to 8 minutes. Scrape the mushrooms in a bowl; set aside.
Wipe out the skillet and return it to the burner. Add the oil; when it ripples, add the onion and cook until translucent, about 6 minutes. Add the garlic and bell pepper and cook 1 minute longer. Season generously with salt.
Add the beef, reduce the heat to medium, and cook, breaking the beef up with a spoon into small clumps. Stop when the meat is no longer pink, about 8 minutes.
- Add the tomatoes and seasoning:
Use your hands to crush the tomatoes directly into the pan (wear an apron) and add the remaining juices from the can.
Add the tomato paste, oregano, pepper flakes, and black pepper and simmer until saucy, about 20 minutes. Add the reserved mushrooms; simmer 2 minutes longer. Taste and adjust the seasoning as needed with salt.
- Meanwhile, boil the pasta:
As the sauce cooks, bring a large pot of salted water to boil. Add the pasta and cook until it still retains a bit of bite. Drain.
- Assemble the casserole:
Return the pasta to the pot; add the cooked sauce and toss. Mix in half of the cheeses, then dump into the greased dish. Scatter the remaining grated cheese on top.
- Bake:
Bake until the sauce bubbles and the cheese is lightly browned, about 30 minutes. Let rest 10 minutes before serving.
