Ultra Creamy Tomato Garlic Penne Pasta Step-by-step instructions

Before you start

Before you start, have all your ingredients prepped and measured: mince the garlic, dice the onion, shred the cheddar, and grate the parmesan. Boil the penne according to package directions until al dente, then drain and set aside.

Reserve about a cup of pasta water in case you need to loosen the sauce. Set a large skillet over medium heat and gather your utensils — you’ll be moving quickly once you start cooking.

Instructions

Sizzling Aromatics

1. 1Sizzle the aromatics
   Melt the butter with the olive oil in a large skillet over medium heat. Add the minced garlic and diced onion, and cook, stirring frequently, until the onion is translucent and the garlic is fragrant, about 2 minutes. Do not let the garlic brown too quickly.
   Look for The onion softens and turns translucent, and the garlic smells sweet and nutty.
   Tip Keep the heat at medium so the garlic cooks gently without burning, which would turn bitter.
2. 2Caramelize the tomato paste
   Add the tomato paste, garlic powder, black pepper, and salt. Cook, stirring constantly, for 3 minutes until the paste darkens to a brick-red color and deepens in flavor. The mixture will look thick and a bit pasty.
   Look for The paste turns a darker, rusty red and smells intensely tomatoey and sweet.
   Tip Stir often to prevent the paste from sticking to the bottom of the skillet.

The butter is melted and bubbling with the olive oil, and the garlic and onion are softening. The kitchen smells fragrant and sweet, with the garlic just beginning to turn golden at the edges but not brown.

The onion should look translucent and tender, and the mixture should be sizzling gently. Stir frequently to keep everything from sticking.

Building the Sauce

3. 3Build the creamy sauce
   Pour in the heavy cream and whisk vigorously, scraping up any browned bits from the bottom of the skillet. Bring the sauce to a gentle simmer and let it cook for 2 minutes, whisking occasionally, until it thickens slightly and turns a silky blush-pink color.
   Look for The sauce becomes smooth, glossy, and a warm pinkish-orange from the tomato paste.
   Tip Whisking constantly helps the cream incorporate smoothly with the tomato paste.
4. 4Melt in the cheeses
   Lower the heat to medium-low. Add the shredded cheddar and grated parmesan, a handful at a time, stirring after each addition until the cheese is fully melted and the sauce is smooth. Continue to cook for another minute until the sauce is thick and velvety.
   Look for The cheese melts into a thick, glossy sauce that coats the back of a spoon.
   Tip Adding cheese gradually prevents clumping and gives a smoother sauce.
5. 5Toss in the penne
   Add the boiled penne pasta to the skillet and toss well with tongs or a spatula until every tube is coated in the creamy sauce. Let it cook for 1 minute so the pasta absorbs some of the sauce and everything is heated through.
   Look for Each penne is coated in a thick, creamy sauce; the pasta looks glossy and well dressed.
   Tip If the sauce seems too thick, add a splash of reserved pasta water to loosen it slightly.

The tomato paste has darkened to a deep brick-red, and the cream has transformed the mixture into a silky blush-pink sauce. The sauce is bubbling gently at the edges and has thickened slightly. The cheese has melted completely, leaving a smooth, glossy texture. The pasta is coated evenly, and the whole skillet looks rich and inviting.

Finishing Touches

6. 6Garnish and serve
   Remove the skillet from the heat. Sprinkle with fresh chopped basil and cracked black pepper. Serve immediately, twirling a forkful of the creamy pasta for the perfect bite.
   Look for The basil adds a fresh green contrast to the pink sauce, and the pepper gives a final kick.
   Tip For extra richness, add a small pat of butter on top just before serving.

The penne is glossy and every piece is coated in the creamy sauce. Fresh basil adds bright green specks, and cracked pepper gives a final aromatic kick. The dish looks luxurious and steamy, with the sauce clinging to the pasta. Give it a final stir and serve immediately for the best texture.

Common mistakes

One common mistake is burning the garlic — keep the heat at medium and stir frequently so it softens without browning too much. Another is not cooking the tomato paste long enough; it should darken to a brick-red color to develop its sweetness.

Also, avoid adding the cheese over high heat, which can cause the sauce to break or become grainy. Finally, don’t overcook the pasta — it will continue to cook slightly in the sauce, so aim for al dente.

How to tell it’s done

The dish is done when the sauce is thick enough to coat the back of a spoon and the pasta is tender but still has a slight bite. The cheese should be fully melted and the sauce should be glossy and smooth, not greasy or separated.

Taste a piece of penne — it should be creamy and well seasoned. Since there is no raw protein, there is no minimum internal temperature to check, but everything should be hot and steamy when served.
