One-Pan Rustic Tomato Pepper Shell Pasta Step-by-step instructions

Before you start

Before cooking, bring a large pot of salted water to a boil and cook the pipe rigate pasta until al dente, according to package instructions. Drain and set aside.

Meanwhile, prep the vegetables: wash the tomatoes and peppers, peel the onion and cut into quarters, and separate the garlic cloves.

Have all the ingredients measured and within reach. The sauce comes together quickly, so having everything ready ensures smooth cooking.

Instructions

Blister and Simmer

1. 1Blister the vegetables
   Heat the olive oil in a large skillet over medium-high heat. Add the whole tomatoes, sweet red peppers, quartered onion, and garlic cloves. Cover with a glass lid and let them steam and blister for about 10 minutes, turning occasionally, until the skins are charred and the vegetables are very soft.
   Look for The vegetables are soft, blistered, and fragrant.
   Tip Use a heavy skillet to get good charring without burning.
2. 2Crush and simmer the sauce
   Remove the lid and crush the softened tomatoes, peppers, and roasted garlic directly in the pan with a wooden spoon. Pour in the vegetable broth and season with salt, black pepper, and chili flakes. Bring to a simmer and cook for 5–7 minutes, stirring occasionally, until the sauce thickens slightly.
   Look for The sauce is thick, bubbling, and rich in color.
   Tip Crush the vegetables well for a rustic, chunky texture.

After this phase, the vegetables are soft, blistered, and fragrant, with charred spots. The sauce is bubbling and has thickened slightly. Check that the tomatoes and peppers are easily crushed with a wooden spoon; if not, continue cooking for a few more minutes.

Toss and Melt

3. 3Toss in the pasta
   Add the boiled al dente pipe rigate shell pasta directly into the sauce. Toss well to coat every shell in the tomato pepper sauce.
   Look for The pasta is evenly coated with sauce.
   Tip Use a wooden spoon or tongs to toss gently without breaking the shells.
4. 4Melt in the cheese
   Sprinkle the shredded kaşar cheese and fresh chopped parsley over the pasta. Toss continuously over medium heat until the cheese is fully melted and the sauce is creamy and glossy.
   Look for The cheese is melted and the pasta is creamy.
   Tip Add the cheese gradually for a smoother melt.

The pasta is coated in sauce, and the cheese is fully melted, creating a creamy, glossy finish. The pan should be sizzling, and the aroma of roasted garlic and tomatoes should fill the kitchen. Ensure the cheese is not sticking to the bottom.

Serve and Enjoy

5. 5Serve immediately
   Scoop the cheesy, saucy pasta into bowls. Garnish with extra parsley or chili flakes if desired, and serve hot.
   Look for The pasta is hot, creamy, and aromatic.
   Tip Serve right away for the best texture.

The pasta is hot, creamy, and aromatic. Each shell is coated in sauce and cheese. Serve immediately, as the dish is best fresh. If desired, garnish with extra parsley and chili flakes.

Common mistakes

A common mistake is overcooking the vegetables, which can make them mushy and lose their charred flavor. Keep the heat medium-high and check them after 8 minutes. Another issue is adding too much broth, resulting in a thin sauce.

Start with 1 cup and simmer until it thickens. Also, avoid boiling the pasta too soft; al dente holds up better when tossed in the sauce. Finally, add the cheese gradually and stir constantly to prevent clumping.

How to tell it’s done

The dish is done when the sauce is thick and coats the back of a spoon, the pasta is tender but still has a slight bite, and the cheese is fully melted and creamy. The vegetables should be completely soft and easily crushed with a wooden spoon.

Taste the sauce before adding the pasta and adjust the seasoning with salt and pepper. The final texture should be saucy but not watery, with the cheese clinging to every shell.
