Save to Pinterest I started making this pasta on a weeknight when I had exactly twenty minutes before my friend showed up for dinner. The promise of one pot and no draining sold me immediately. What I didn't expect was the way the steam would carry that first hit of garlic and red pepper through the kitchen, sharp and warm at the same time, or how the pasta would drink up all that tomato-spiked broth and turn silky without any cream.
The first time I served this, I made it too spicy by accident and had to pass around a bowl of Parmesan like a peace offering. My sister still brings it up. But that night also taught me that the cheese does more than finish the dish, it actually mellows the heat and ties everything together, turning sharp edges into something round and comforting.
Ingredients
- Penne or rigatoni: These shapes have ridges and hollows that trap the sauce, and they hold up to the full cooking time without turning mushy.
- Water or vegetable broth: Broth adds a deeper background flavor, but water works beautifully if you let the tomatoes and seasoning do the talking.
- Red onion: It softens into sweetness and adds a slight purple blush to the oil, which I find prettier than yellow onion.
- Garlic cloves: Minced fine so they melt into the sauce and release their fragrance the second they hit the heat.
- Red bell pepper: Thinly sliced so it cooks down into tender ribbons that almost disappear into the sauce but leave behind a faint smoky sweetness.
- Canned diced tomatoes: Use the whole can, juice and all, because that liquid becomes part of the cooking broth and carries the tomato flavor into every strand of pasta.
- Olive oil: Just enough to coat the bottom of the pan and give the onion and garlic a place to bloom without sticking.
- Italian seasoning: A blend that usually includes basil, oregano, and thyme, and it brings the whole dish into focus without having to measure out five separate jars.
- Crushed red pepper flakes: This is where the diavola heat lives, start with less if youre cautious, you can always add more at the table.
- Smoked paprika: It adds a faint campfire depth that makes the sauce taste more complex than it actually is.
- Salt and black pepper: Season as you go, the pasta will absorb a lot of the salt from the cooking liquid, so taste before serving.
- Parmesan cheese: Grated fresh, not the dusty kind from a can, it melts into the residual heat and makes everything creamy.
- Fresh parsley or basil: Chopped at the last second so the color stays bright and the flavor stays green and alive.
- Lemon zest: Optional, but it cuts through the richness and wakes up the whole plate with one or two quick scrapes of the grater.
Instructions
- Start with the aromatics:
- Heat the olive oil over medium heat until it shimmers, then add the chopped onion and let it cook until the edges go translucent and the kitchen smells sweet. This takes about three minutes, and its worth the wait.
- Build the base:
- Stir in the garlic and red bell pepper, letting them sizzle together for two minutes until the garlic turns golden and the pepper starts to soften. Dont rush this part, the flavor youre building here carries the whole dish.
- Add everything else:
- Pour in the diced tomatoes with all their juices, then add the pasta, water or broth, Italian seasoning, red pepper flakes, smoked paprika, salt, and black pepper. Stir it all together so the pasta is mostly submerged and nothing sticks to the bottom.
- Simmer and stir:
- Bring the pot to a boil, then lower the heat to a gentle simmer and cook uncovered for twelve to fourteen minutes, stirring every few minutes so the pasta doesnt clump. Youll know its done when the pasta is al dente and most of the liquid has been absorbed into a thick, clingy sauce.
- Finish and serve:
- Pull the pot off the heat and stir in the grated Parmesan and lemon zest if youre using it. Taste and adjust the salt or pepper, then serve it hot with a handful of fresh herbs and extra cheese on top.
Save to Pinterest There was a night last winter when I made this for myself after a long day, and I ate it straight from the pot with a wooden spoon, standing at the stove. The heat from the pepper and the warmth from the steam mixed together, and I realized this dish didnt need an occasion or a table set for guests. It just needed to be made and eaten while it was still too hot, with all the urgency and comfort that implies.
How to Adjust the Heat Level
Start with one teaspoon of red pepper flakes if youre unsure, then taste the sauce halfway through cooking and add more if you want it fierier. The heat builds as it simmers, so what tastes mild at the beginning can surprise you by the end. If you go too far, stir in an extra handful of Parmesan or a drizzle of cream to calm it down without diluting the flavor.
Storage and Reheating
This pasta keeps in the fridge for up to three days in an airtight container, though the noodles will soak up more sauce as they sit. When you reheat it, add a few tablespoons of water or broth to loosen it back up, and warm it gently in a skillet over low heat, stirring often. It tastes almost better the next day once the flavors have had time to settle into each other.
Variations and Add-Ins
If you want protein, sliced cooked chicken sausage or sauteed shrimp stirred in at the end turns this into a full meal without adding another pan. For a vegan version, swap the Parmesan for nutritional yeast and use vegetable broth instead of water. You can also throw in a handful of spinach or kale in the last two minutes of cooking, it wilts right into the sauce and adds color without changing the spirit of the dish.
- Try swapping the red bell pepper for cherry tomatoes, halved, they burst into little pockets of sweetness.
- A splash of white wine added with the tomatoes makes the sauce taste brighter and more complex.
- Fresh mozzarella torn on top just before serving melts into creamy pockets that contrast with the spicy sauce.
Save to Pinterest This is the kind of pasta that makes you feel capable on a weeknight, the kind that fills the kitchen with good smells and clears your head while you stir. I hope it does the same for you.
