Possibly the fastest spaghetti dinner you’ll ever make. Once you cook pasta this way, you will NEVER go back to boiling water on the stove!
Why I Love This Recipe
Hey there, pasta lovers! It’s Chef AJ, your Queen of Quick and Easy Plant-Based Recipes! If there’s one technique that has revolutionized weeknight dinners in my kitchen, it’s this one. Just three ingredients, one pot, and four minutes of pressure cooking—no waiting for water to boil, no draining, no extra dishes. The pasta cooks right in the sauce, which means every noodle is infused with flavor.
Key Ingredients
- Gluten-Free Brown Rice Pasta: I use Jovial brand—it holds its texture beautifully in the Instant Pot and no one will ever guess it’s gluten-free.
- Marinara Sauce: I use Whole Foods Fat-Free & Sugar-Free Marinara. Warm it before adding so the pot comes to pressure quickly.
- Boiling Water: Starting with boiling water is the secret to the 4-minute timing—it gets the pot to pressure fast so the pasta cooks perfectly.
The Process
Evenly place the pasta on the bottom of the Instant Pot, pour boiling water over the noodles, and add the warmed marinara sauce. Cook on high pressure for just 4 minutes, release the pressure, and stir well. Put the lid back on for a few minutes and the sauce will thicken to saucy perfection.
Chef’s Tips
- Use warmed sauce and boiling water—this is what makes the 4-minute timing work.
- The sauce may look thin right after cooking—stir well, put the lid back on for a few minutes, and it will thicken right up.
- Serve the warm marinara pasta over a chilled Caesar salad for a delicious contrast and a lower calorie density meal—that’s my Caesar Salad Pasta!
How to Store
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave with a splash of water to loosen the sauce.
