Ingredients
- 12 ounces (340 g) dry penne pasta or your favorite short pasta
- 1 pint (about 2 cups) cherry tomatoes, halved
- 3 cups low-sodium vegetable or chicken broth
- 3 cloves garlic, minced
- 1 small yellow onion, finely chopped
- 1/4 cup fresh basil leaves, roughly chopped
- 2 tablespoons olive oil
- 1/2 teaspoon red pepper flakes (optional, for a mild heat)
- Salt and freshly ground black pepper, to taste
- 1/2 cup freshly grated Parmesan cheese, plus extra for serving
- Juice of half a lemon (optional, for brightness)
Instructions
- Sauté aromatics: Set the Instant Pot to the Sauté mode and heat the olive oil. Add the chopped onion and cook for about 3 minutes until translucent. Stir in the minced garlic and red pepper flakes, cooking for 30 seconds until fragrant—be careful not to burn the garlic.
- Add tomatoes and seasoning: Toss in the halved cherry tomatoes, stirring for another 2 minutes so they start to soften. Season with a pinch of salt and pepper.
- Combine pasta and broth: Pour in the dry pasta and spread it evenly over the tomato mixture. Pour the broth over the pasta but do not stir; this helps prevent the pasta from sticking together.
- Pressure cook: Seal the Instant Pot lid and set the valve to sealing. Cook on Manual/Pressure Cook high pressure for 4 minutes. (Most penne pasta takes 9-11 minutes to cook traditionally, but pressure cooking halves that time.)
- Quick release and finish: When the cooking time is up, perform a quick release by carefully turning the valve to venting. Open the lid and stir the pasta, breaking up any clumps. If the sauce seems too thin, use the Sauté mode to simmer and reduce for 2-3 minutes.
- Add basil and cheese: Stir in the chopped fresh basil, grated Parmesan, and lemon juice if using. Adjust seasoning with extra salt and pepper as needed.
- Serve immediately: Dish out the pasta onto plates and sprinkle with additional Parmesan and fresh basil leaves for garnish.
Tips
- Substitutions: You can swap penne for other short pasta shapes like rigatoni, fusilli, or farfalle—just adjust cooking times slightly. Use vegetable broth to keep it vegetarian or chicken broth for richer flavor.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. The pasta may absorb more liquid; add a splash of broth or water when reheating to loosen it.
- Common mistakes: Avoid stirring the pasta and broth before pressure cooking to prevent sticking and burning at the bottom. Also, do not overcook the pasta under pressure—4 minutes is ideal for al dente penne.
- Freshness matters: Using fresh basil at the end preserves its bright flavor and aroma. Dried basil can be added earlier, but the fresh finish is key.
Serving Suggestions
This cherry tomato and basil pasta pairs beautifully with a simple green salad dressed with lemon vinaigrette or a side of garlic bread for a classic Italian touch. For a protein boost, add grilled chicken, sautéed shrimp, or a dollop of ricotta cheese on top. A crisp white wine like Pinot Grigio or Sauvignon Blanc complements the fresh, bright flavors well.
Variations
Try adding other vegetables such as spinach, zucchini ribbons, or roasted bell peppers for extra color and nutrition. For a creamier sauce, stir in 1/4 cup of heavy cream or mascarpone cheese at the end. You can also incorporate olives or capers to add a briny depth. For a vegan version, omit Parmesan and top with nutritional yeast or vegan cheese alternatives.
Storage and Reheating
Store any leftover pasta in an airtight container in the fridge for up to 3 days. When reheating, gently warm it in a skillet over medium heat with a splash of broth or water to prevent dryness and help loosen the sauce. Alternatively, microwave in short intervals, stirring in between and adding liquid as needed. Avoid reheating multiple times to maintain quality and food safety.
Frequently Asked Questions
- Can I use frozen cherry tomatoes for this recipe?
- Frozen cherry tomatoes can be used if fresh aren’t available, but they will release more water, potentially thinning the sauce. You may want to reduce the broth slightly or simmer longer after cooking to thicken the sauce.
- What if I don’t have an Instant Pot?
- You can make this on the stovetop by sautéing the aromatics and tomatoes, then adding broth and pasta, cooking until al dente while stirring occasionally. It will take about 12-15 minutes. The Instant Pot speeds up the process and requires less attention.
- How do I prevent the pasta from sticking in the Instant Pot?
- To avoid sticking, do not stir the pasta once you add the broth. Spread the pasta evenly and pour the liquid over the top to help keep it separate. Using enough broth (3 cups for 12 ounces of pasta) also helps.
- Can I make this recipe gluten-free?
- Yes, use gluten-free pasta varieties and ensure your broth is gluten-free as well. Cooking times may vary slightly depending on the pasta brand, so monitor doneness closely.
- Is it better to add basil before or after cooking?
- Adding fresh basil after cooking preserves its bright, fresh flavor and aroma. If using dried basil, add it during the sauté step so it can infuse the dish with deeper flavor.
- Can I double this recipe for a larger group?
- You can double the ingredients, but be cautious not to overfill your Instant Pot. Follow the manufacturer’s max fill line for liquids and solids. Cooking time remains the same, but you may need to increase the natural release time slightly.
This cherry tomato and basil Instant Pot pasta recipe balances ease and freshness, making it a go-to for quick, flavorful meals. Its versatility and minimal prep make it a kitchen favorite year-round.
