Penne Pasta Recipe Veg: Garlicky Tomato Basil Delight

This vegetarian penne dish brings Italian comfort to your table with minimal effort. The secret lies in a garlicky tomato sauce that simmers while the pasta cooks, infusing every bite with bold flavor.

I developed this recipe in my tiny Boston kitchen, testing it repeatedly to ensure it works in any home cook’s space. The combination of ripe tomatoes, fresh basil, and plenty of garlic creates a sauce that’s both simple and deeply satisfying.

What emerges is a plate of al dente penne coated in a rich, aromatic sauce with tender vegetable pieces throughout. The basil adds a fresh finish that brightens the entire dish.

Ready in under 30 minutes, this meal proves vegetarian cooking can be both quick and deeply flavorful.

Simple ingredients for a bold Italian-inspired vegetarian plate at home.

The tomatoes are key here. San Marzano crushed tomatoes from a can give the best texture—sweet, thick, and not watery. I grab mine from Whole Foods or Trader Joe’s (their store brand is solid). The garlic should be fresh; those jarred minced ones just don’t hit the same. For the basil, grab a bunch with bright green leaves (no wilted stems) from the produce section.

No San Marzano? Any canned crushed tomatoes work, but avoid the ones with added herbs. Out of fresh basil? Dried basil at one-third the amount works in a pinch, but add it earlier in cooking. Swap the bell pepper for zucchini if that’s what you’ve got. The Parmesan is optional but honestly worth the extra minute to grate fresh from a wedge.

Cooked pasta and sauce keep together in the fridge for 4-5 days. Freeze the sauce alone for up to 3 months. The basil is best fresh, so add it just before serving (frozen works in a pinch).

Step-by-Step Instructions for Garlicky Tomato Basil Penne

Here’s my no-fail method for building layers of flavor in this simple but stunning dish.

Step 1: Sauté Aromatics Until Fragrant

Heat the 0.25 cup Extra-Virgin Olive Oil in a large, deep skillet over medium heat. Add the finely diced 1 whole Yellow Onion and cook for 4-5 minutes until it turns translucent and soft. This builds the sweet base that balances the acidity of the tomatoes.

Next, stir in the minced 6 cloves Garlic Cloves, diced 1 whole Red Bell Pepper, 1 tsp Dried Oregano, 0.5 tsp Red Pepper Flakes, 1 tsp Salt, and 0.5 tsp Black Pepper. Cook for another 2-3 minutes until the garlic is golden and fragrant but not browned. Real talk: Burnt garlic turns bitter, so keep it moving.

Step 2: Simmer the Tomato Sauce to Perfection

Pour in the 28 oz Canned Crushed Tomatoes and 0.5 cup Vegetable Broth, stirring to scrape up any browned bits from the bottom. Increase heat to medium-high and bring to a gentle simmer.

Reduce heat to medium-low and let the sauce simmer uncovered for 15-20 minutes, stirring occasionally. You want it to thicken slightly and deepen in color to a rich, ruby red. This is where the magic happens—the flavors meld and the raw tomato taste mellows out.

Step 3: Cook Pasta Al Dente and Combine

While the sauce simmers, bring a large pot of salted water to a rolling boil and cook the 12 oz Penne Pasta according to package directions until al dente (about 1 minute less than suggested). Reserve ½ cup of pasta water before draining.

Add the drained penne directly to the skillet with the sauce. Toss everything together over medium heat for 1-2 minutes, adding a splash of reserved pasta water as needed to help the sauce cling to the pasta. The starch in the water helps create that perfect, glossy coating.

Step 4: Finish with Fresh Basil and Serve

Remove the skillet from heat and stir in the torn 1 cup Fresh Basil Leaves. The heat from the pasta will gently wilt the basil, releasing its aroma without turning it muddy. Taste and adjust seasoning if needed—I often add a pinch more salt here.

Divide the pasta among serving bowls and top each with a generous sprinkle of 0.5 cup Parmesan Cheese. Serve immediately while hot—the cheese will melt slightly from the residual heat, creating little pockets of gooey goodness throughout. This dish is best enjoyed fresh, with a side of crusty bread to soak up every last bit of sauce.

Storing and Reheating This Recipe

Refrigerator Storage

Let your penne cool for no more than 2 hours before transferring to airtight containers. I use glass Pyrex with snap-on lids from my local Boston market. Store at 40°F or below for up to 4-5 days. The flavors actually improve overnight as the herbs meld together. ❄️

Freezer Storage

This dish freezes well for up to 3 months without significant quality loss. I recommend flat freezer bags because they stack efficiently in my tiny apartment freezer. Leave 1 inch of headspace for expansion and squeeze out excess air to prevent freezer burn.

Stovetop Reheating

This is my preferred method because it maintains the best texture. Pour pasta into a heavy-bottomed pot, add ¼ cup water or vegetable broth to prevent sticking, and heat over medium-low heat for 10-15 minutes. Stir occasionally and add a splash of water if it looks dry. 🔥

Microwave Reheating

For quick lunches, microwave individual portions covered with a damp paper towel. Heat on 70% power for 2-3 minutes, stir, then continue in 1-minute intervals until reaching 165°F. The basil may darken slightly, but the flavor remains vibrant.
