Craving a comforting, luxurious pasta without the pile of dishes? This Easy One Pot Creamy Tomato Pasta delivers rich flavor and a silky sauce with minimal cleanup.

Ingredients

The beauty of this one-pot pasta lies in simple, fresh ingredients. Using ripe, fresh tomatoes will give the sauce a vibrant sweetness, but a quality tin of chopped tomatoes works perfectly for convenience.

500 g fresh tomatoes, chopped (or use 1 x 400 g tin of chopped tomatoes)
2 tbsp olive oil
3 cloves garlic, minced
1 onion, finely chopped
500 ml chicken or vegetable stock (use a stock cube for convenience)
150 ml double cream
½ bunch fresh basil

Step-by-Step Instructions

Step 1 — Sauté the Aromatics

Heat the olive oil in a large, deep pan or Dutch oven over medium heat. Add the finely chopped onion and cook for 4-5 minutes until softened and translucent. Stir in the minced garlic and cook for another minute until fragrant. (Pro tip: Sautéing the onion first allows its natural sugars to caramelize, building a deeper flavor base for your creamy tomato pasta).

Step 2 — Add Tomatoes and Stock

Add the chopped fresh tomatoes (or the tinned tomatoes) to the pot. Pour in the chicken or vegetable stock and give everything a good stir, scraping up any bits from the bottom of the pan. Bring the mixture to a gentle simmer.

Step 3 — Cook the Pasta

Break the spaghetti in half and submerge it into the simmering liquid, ensuring it’s mostly covered. Reduce the heat to medium-low, cover the pot, and let it cook for 10-12 minutes. Stir occasionally to prevent sticking. The pasta will absorb the flavorful liquid as it cooks.

Step 4 — Check for Doneness

After 10 minutes, uncover and test a strand of pasta. It should be al dente—tender but with a slight bite. If needed, cook for another 1-2 minutes, but note the sauce will continue to thicken. The liquid should be significantly reduced but still saucy.

Step 5 — Incorporate the Cream

Turn off the heat. Pour in the double cream and stir gently until the sauce becomes luxuriously creamy and turns a lovely pale orange color. In my tests, adding the cream off the heat prevents any risk of curdling and ensures a smooth, velvety texture.

Step 6 — Finish with Fresh Basil

Tear the fresh basil leaves by hand and stir most of them through the pasta. This preserves their delicate aroma better than chopping. Season generously with salt and black pepper to taste. Serve immediately, garnished with the remaining basil leaves.

Common Mistakes to Avoid

Mistake: Using a pot that’s too small. Fix: The pasta needs room to be submerged; a Dutch oven or large, deep sauté pan prevents uneven cooking and boil-overs.
Mistake: Adding the cream while the pot is still on high heat. Fix: Always turn off the heat first, as in Step 5, to ensure a smooth, uncurdled sauce.
Mistake: Not stirring occasionally during cooking. Fix: Stir every 3-4 minutes to prevent the pasta from sticking to the bottom and clumping together.
Mistake: Using cold stock straight from the fridge. Fix: Use warm or room-temperature stock to maintain a steady simmer and consistent cook time.
Mistake: Overcooking the pasta until mushy. Fix: Remember the pasta continues to cook in the residual heat; aim for al dente when testing in Step 4.
Mistake: Skipping the sauté step for the onions and garlic. Fix: This foundational step builds depth of flavor; rushing it results in a one-dimensional sauce.
Mistake: Forgetting to season at the end. Fix: Always taste and adjust salt and pepper after adding the cream, as it can dilute the seasoning.

Storing Tips

Fridge: Cool completely, then store in an airtight container for up to 5 days. The sauce will thicken; add a splash of stock or water when reheating.
Freezer: Portion into freezer-safe containers, leaving 1-inch headspace. Freeze for up to 3 months. Thaw overnight in the fridge for best texture, as freezing can slightly alter the cream’s consistency.
Reheat: Gently warm in a saucepan over medium-low heat with a tablespoon of water or stock, stirring frequently. For the microwave, use a covered dish and reheat in 60-second intervals, stirring in between, until it reaches 165°F (74°C).

This easy one-pot pasta is a fantastic make-ahead meal. In my tests, the flavors meld and deepen when stored, making leftovers a delicious advantage for your weekly plan.

Frequently Asked Questions

How many servings does this easy one pot creamy tomato pasta make?

This recipe yields 3-4 generous servings. For accurate portioning, the 250g of pasta and 500ml of stock are calibrated to serve three as a main course or four as part of a larger meal with sides like a salad or bread. You can easily double all ingredients in a large Dutch oven to serve a crowd.

What can I use if I don’t have fresh basil?

Fresh basil can be substituted with 1-2 teaspoons of dried basil added with the tomatoes, or 2 tablespoons of prepared pesto stirred in with the cream. For a different herbal note, fresh parsley or oregano work well. In my tests, a teaspoon of dried Italian seasoning is a reliable pantry swap that still delivers great flavor.

Why is my one pot pasta sauce too watery?

A watery sauce usually means there was too much liquid or not enough reduction time. Unlike traditional methods, the pasta should absorb most of the stock. The fix is simple: simmer uncovered for an extra 3-5 minutes after adding the cream to thicken the sauce. Remember, the sauce will continue to thicken slightly as it cools on the plate.
