Vegan One-Pot Pasta Ingredients
Here’s everything you’ll need:
- Linguine. Other long pastas work too; cooking time may vary.
- Garlic. Minced for best integration.
- Onion. Diced and softened first for deeper flavor.
- Crushed red pepper. For a touch of heat.
- Salt & pepper.
- Olive oil.
- Tomato sauce. Use your favorite marinara or spaghetti sauce.
- Basil. Half cooked in, half reserved fresh for garnish.
Tested Substitutions
Spaghetti or fettuccine can replace linguine; just check for doneness a few minutes earlier or later depending on thickness. This recipe is vegan-friendly—top with vegan Parmesan, nutritional yeast, or dairy Parmesan if you prefer.
That said, the pasta is delicious as-is—no cheese required.
One-Pot Pasta Marinara Tips and Tricks
Cook Your Onion First
Sauté diced onion in olive oil over medium heat for about 5–7 minutes, until translucent and fragrant. This step lets the onion soften and meld with the sauce so the final dish tastes balanced and well-rounded.
Snap Your Pasta in Half If You Must
If a long pasta won’t fit in your pot, breaking it in half is perfectly fine. Laying the strands flat over the onions helps them cook evenly and absorb sauce better.
Add It All to the Pot
After the onions are softened, add the pasta, water, tomato sauce, seasonings, minced garlic, and half the basil. Cover and bring to high heat. Cooking the pasta directly in the sauce and a little water reduces dishes and infuses the noodles with tomato flavor.
Cook Your Pasta and Sauce All in One Pot
Cover the pot and cook on high for 12–14 minutes, stirring occasionally. Taste after 12 minutes—you’re aiming for al dente. When the pasta is nearly there, remove the lid, lower the heat to a gentle simmer, and cook uncovered until the sauce reaches your preferred thickness.
Make It Your Own
This recipe is a versatile foundation—add seasonal vegetables or greens for extra texture and nutrition. Sauté any vegetables with the onions in step two so they cook through. Good additions include arugula, spinach, mushrooms, squash, or zucchini, but feel free to experiment.
