One-Pan Roasted Vegetable and Meatball Mashed Penne Ragù Step-by-step instructions

Before you start

Before you begin, bring a large pot of salted water to a boil and cook the penne until al dente according to package directions. Drain and set aside.

Prepare the vegetables: wash the tomatoes and zucchini, cut the zucchini into thick cylinders, and peel the garlic cloves. Have all ingredients measured and ready, as the cooking process moves quickly once the skillet is on the heat.

Instructions

Roast and Mash

1. 1Sear the Vegetables and Meatballs
   Heat the olive oil in a large wide skillet over medium-high heat. Add the whole tomatoes, zucchini cylinders, garlic cloves, and beef meatballs in a single layer. Cover the skillet and let everything steam and roast for 12 minutes, turning the meatballs once halfway through, until the tomatoes are blistered and the meatballs are browned on the outside.
   Look for The tomatoes will blister and release juice, the zucchini softens, and the meatballs brown.
   Tip Keep the heat medium-high to get a good sear without burning the garlic.
2. 2Mash into a Chunky Ragù
   Uncover the pan. Using a heavy potato masher, crush the softened tomatoes, roasted zucchini, and tender meatballs directly in the pan. Mash until you have a thick, chunky bolognese-style ragù with some texture remaining. Continue to cook for 2 minutes, stirring occasionally, so the mixture thickens slightly.
   Look for The ragù should look like a coarse, rustic sauce with visible chunks of meat and vegetables.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Do not over-mash; leave some hearty pieces for texture.

After 12 minutes, the tomatoes should be blistered and softened, the zucchini tender, and the meatballs browned on the outside. The pan will be fragrant with roasted garlic.

When you mash, you should see thick, chunky pieces of meat and vegetables, not a watery liquid. The mixture should hold its shape when stirred.

Season and Combine

3. 3Season and Simmer
   Stir in the sea salt, black pepper, dried oregano, and chili flakes. Let the ragù simmer over medium-low heat for 5 minutes, stirring occasionally, until the flavors meld and the sauce deepens in color.
   Look for The sauce will bubble gently and smell fragrant with oregano and chili.
   Tip Taste the ragù and adjust seasoning if needed before adding the pasta.
4. 4Toss with Penne
   Add the cooked penne pasta to the skillet. Use tongs to toss the pasta thoroughly with the ragù until every piece is coated. Cook for 2 minutes, allowing the pasta to absorb some of the sauce.
   Look for The penne will be evenly coated with the thick, meaty sauce.
   Tip If the sauce seems too thick, add a splash of pasta water to loosen it.
5. 5Melt the Cheese Through
   Sprinkle the shredded mozzarella over the pasta. Cover the skillet for 1 minute to let the cheese melt, then uncover and toss gently to distribute the melted cheese throughout the pasta.
   Look for The cheese will be melted and stretchy, clinging to the pasta.
   Tip Use a low heat to avoid burning the cheese.

The ragù should be bubbling gently, with the oregano and chili flakes perfuming the air. The sauce will have thickened slightly, and the color will be deep red. When you add the penne, the pasta should be evenly coated without the sauce pooling at the bottom. The cheese should melt into glossy strands.

Finish and Serve

6. 6Finish and Serve
   Remove the skillet from the heat. Sprinkle the chopped parsley over the top and toss once more. Serve immediately, twirling a forkful of the rich, saucy pasta to show off the thick ragù.
   Look for The parsley adds a fresh green contrast to the deep red sauce.
   Tip Serve directly from the skillet for a rustic, family-style presentation.

The parsley adds a fresh green pop. The pasta should be glistening with sauce and cheese, and the meatballs should be integrated throughout. A forkful should twirl easily, with the ragù clinging to the penne. The skillet should be practically clean — that’s the sign of a perfect one-pan dish.

Common mistakes

A common mistake is using low heat during the initial roasting, which prevents the tomatoes from blistering and the meatballs from browning. Another is over-mashing the mixture into a smooth paste — you want a chunky ragù.

Also, be careful not to overcook the pasta before adding it to the sauce; slightly undercooking (al dente) ensures it holds up when tossed and simmered.

How to tell it’s done

The ragù is done when the meatballs reach an internal temperature of 160°F (71°C) and the vegetables are completely soft and easily mashed. The sauce should be thick and chunky, not watery.

When you toss the pasta, it should be well coated with the ragù, and the cheese should be fully melted and stretchy. Taste and adjust seasoning before serving.
