Ingredients
Main Ingredients
- 1 pound penne pasta
- 4 cups vegetable broth
- 1 can (15 oz) crushed tomatoes
- 1 cup heavy cream or coconut cream
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
Spices and Seasonings

- 1 teaspoon dried oregano
- 1 teaspoon sugar
- Salt and black pepper to taste
Optional Garnish
- Fresh basil leaves
This dish starts with penne pasta, which is the perfect shape for soaking up sauce. The vegetable broth adds flavor and moisture. Crushed tomatoes give this dish its rich, bright color. Heavy cream or coconut cream makes it creamy. The cheeses add a wonderful cheesy taste, making it comforting and satisfying.
For spices, I use garlic powder and onion powder for a nice base flavor. Dried oregano brings a touch of earthiness. A little sugar balances the acidity of the tomatoes, while salt and black pepper enhance all the flavors.
Fresh basil leaves are a great way to finish your dish. They add a burst of freshness and a pop of color. You can use them as a garnish or mix them in for extra flavor.

Step-by-Step Instructions
Preparing the Instant Pot
First, power on your Instant Pot. Select the “Sauté” function. Wait a moment for it to warm up. This step preps the pot for cooking.
Combining Pasta and Broth
Next, add the vegetable broth. Pour in 4 cups. Then, add 1 pound of penne pasta. Use a spoon to stir gently. Make sure all pasta is submerged.
Mixing in Tomatoes and Spices
Now, incorporate the crushed tomatoes. Add 1 can, then mix in seasonings. Include 1 teaspoon each of garlic powder, onion powder, and dried oregano. Add 1 teaspoon of sugar, salt, and pepper to taste. Stir well to combine all ingredients.
Cooking the Pasta
Secure the lid on the Instant Pot. Make sure the sealing valve is closed. Choose the “Manual” or “Pressure Cook” option. Set the timer for 6 minutes.
Quick Release Method
When the timer beeps, perform a quick release. Carefully turn the valve to venting. Once the steam stops, you can safely open the lid.
Finishing Touches
Stir in 1 cup of heavy cream or coconut cream. Add 1 cup of shredded mozzarella cheese and half a cup of Parmesan cheese. Mix until everything is creamy and well-blended. For a baked finish, transfer to a greased baking dish. Sprinkle the rest of the Parmesan on top. Broil for 5-7 minutes until golden brown. Serve warm, garnished with fresh basil leaves.
Tips & Tricks
Perfecting the Creamy Texture
- Choosing the right cream: Use heavy cream for a rich taste. For a dairy-free choice, go with coconut cream. Both make the sauce smooth and tasty.
- Proper mixing techniques: Stir gently when adding cream and cheese. This helps blend them well with the pasta and keeps the sauce creamy. Make sure to mix until everything is combined.
Instant Pot Safety
- Ensuring proper sealing: Always check the sealing ring before cooking. It should fit snugly to prevent steam leaks. This keeps the pressure right for cooking.
- Quick release tips: When the time is up, carefully turn the valve for a quick release. Stand back as steam escapes. This step is important for safety and keeps your pasta from overcooking.
Cooking Time Adjustments
- Modifying for different pasta shapes: If you use other pasta shapes, adjust cooking time. Smaller shapes like macaroni need less time. Larger ones like rigatoni may need a minute more.
- Altitude considerations: At high altitudes, increase the cooking time by a minute or two. This change helps cook the pasta evenly and keeps it from being hard.
Pro Tips
- Salt Your Water: Always add salt to the boiling water before cooking pasta. It enhances the flavor of the pasta itself and can make a big difference in the final dish.
- Use Fresh Basil: For the best flavor, use fresh basil leaves as a garnish. They add a vibrant aroma and enhance the overall taste of the dish.
- Adjust Consistency: If the pasta seems too dry after cooking, add a splash more cream or broth to reach your desired creaminess.
- Save Some Cheese: Reserve a bit of mozzarella and Parmesan cheese to sprinkle on top before broiling for an extra cheesy crust.
Variations
Vegetarian Options
You can easily make this dish vegetarian. Try adding more veggies. Spinach, zucchini, or bell peppers are great choices. Simply chop them and stir them in with the pasta. For a dairy-free option, use coconut cream instead of heavy cream. This keeps the meal rich and creamy without any dairy.
Protein Additions
Want to add some protein? Chicken or shrimp works well. Cook them in the Instant Pot first, then add the pasta. If you prefer a vegan option, use chickpeas or lentils. They cook quickly and blend nicely with the flavors.
Different Pasta Types
Not a fan of penne? You can switch to other pasta shapes like rotini or fusilli. They hold onto the sauce well. If you need gluten-free pasta, look for brands made from rice or chickpeas. They taste great and keep the dish healthy.

FAQs
Can I make this recipe without an Instant Pot?
Yes, you can! Use a large pot on the stove. Start by boiling the vegetable broth. Add the penne pasta and cook until al dente. Once done, drain the pasta and return it to the pot. Stir in the crushed tomatoes, spices, and cream. Heat until warm and mix in the cheeses. For a baked version, transfer to a baking dish and broil for a golden top.
What can I substitute for heavy cream?
If you need a replacement for heavy cream, try using coconut cream. It gives a rich flavor and is dairy-free. Other options include Greek yogurt or cashew cream for a lighter twist. Both options will keep the dish creamy and tasty.
How do I make this dish spicier?
To spice things up, add red pepper flakes or some diced jalapeños. Stir them in with the crushed tomatoes. You can also use a spicy sauce like sriracha. Just start with a little, taste, and add more as needed.
Can I add more vegetables?
Absolutely! Vegetables like spinach, bell peppers, or zucchini work well. Chop them up and add them when you mix in the tomatoes and spices. This will boost the nutrition and flavor of your dish.
How can I make this low-carb?
For a low-carb version, swap the penne pasta with zucchini noodles or spaghetti squash. You can also use shirataki noodles for a very low-carb option. Adjust the cooking time, as these alternatives cook much faster than regular pasta.
