Heat olive oil in a large skillet over medium-high heat. Add diced onion and cook until translucent, about three minutes—you're building a flavor base here, not just softening vegetables. Once the onion is almost clear, add minced garlic and cook for exactly one minute until fragrant but not brown, because burnt garlic tastes bitter and will haunt the whole dish.

Add ground beef to the skillet and break it apart with a wooden spoon. Let it sit undisturbed for two minutes so it browns instead of steaming—this is where the magic happens, and it's the move most home cooks skip. Stir occasionally until the beef releases its water and the water evaporates, which takes about eight minutes total.

Pour marinara sauce into the beef mixture and stir in dried oregano, dried basil, and red pepper flakes. Reduce heat to low and let it simmer for ten minutes while you handle the pasta—this simmering time lets the herbs bloom and the flavors marry instead of tasting like you dumped cold sauce over ground meat.

Meanwhile, bring a large pot of salted water to a rolling boil. Add ziti pasta and cook for two minutes less than the package instructions—the pasta will continue cooking in the oven, and overcooking it now means mush later. I learned this after one mortifying dinner where the baked ziti crowd summer recipe fell apart on the plate because I wasn't paying attention to the package directions.

Drain pasta and let it cool for two minutes in a colander. In a separate bowl, combine ricotta cheese, half the mozzarella, and half the Parmesan cheese—don't skip cooling the pasta slightly because hot pasta will scramble the ricotta and create grainy pockets. This step takes thirty seconds and changes everything about texture.

Preheat oven to 375 degrees Fahrenheit. In a 9x13-inch baking dish, spread a thin layer of meat sauce on the bottom to prevent sticking. Add half the cooled pasta, then half the remaining sauce, then half the cheese mixture. Repeat layers with remaining pasta, sauce, and cheese mixture.

Top the assembled baked ziti crowd summer recipe with remaining mozzarella and sprinkle fresh parsley across the top. Cover the baking dish with foil and bake for thirty minutes, then remove foil and bake for another twenty minutes until the cheese is golden brown and bubbling at the edges. The foil prevents the top from browning too fast while the center heats through.

Remove from oven and let rest for five minutes before serving—this resting period lets the layers set so you can actually serve distinct portions instead of scooping soup into bowls. Trust this step even though you're starving and the aroma is overwhelming.
