500 ml chicken or vegetable stock (use a stock cube for convenience)
150 ml double cream

Step-by-Step Instructions

Step 1 — Sauté the Aromatics

Heat the olive oil in a large, deep skillet or pot over medium heat. Add the finely chopped onion and cook for 4-5 minutes until soft and translucent. Stir in the minced garlic and cook for another minute until fragrant. (Pro tip: Sautéing, which means cooking quickly in a small amount of fat, builds a crucial flavor foundation without burning the garlic).

Step 2 — Add Tomatoes and Stock

Add the chopped fresh tomatoes (or tinned tomatoes) to the pot. Pour in the 500 ml of stock. Increase the heat to bring the mixture to a steady simmer, stirring to combine all the ingredients.

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 a gentle simmer. Let the pasta cook for 12-14 minutes, stirring occasionally to prevent sticking. The pasta will absorb the flavorful liquid as it cooks.

Step 4 — Check for Doneness

After about 12 minutes, test a strand of spaghetti. It should be al dente—tender but with a slight bite. The liquid should have reduced to a thick, saucy consistency that coats the pasta. If it’s too watery, simmer for another 1-2 minutes.

Step 5 — Incorporate the Cream

Once the pasta is cooked and the sauce has thickened, turn off the heat. Stir in the double cream until the sauce becomes luxuriously smooth and creamy. (Pro tip: Adding the cream off the heat prevents any risk of curdling).

Step 6 — Finish and Serve

Tear the fresh basil leaves and stir most of them through the creamy tomato pasta. Season generously with salt and black pepper to taste. Serve immediately, garnished with the remaining basil. This one-pot wonder delivers a restaurant-quality creamy pasta with just one pan to wash.

This easy creamy tomato pasta is incredibly versatile. In summer, use peak-season tomatoes and serve al fresco. It also reheats beautifully, making it a stellar meal-prep option for lunches.

Common Mistakes to Avoid

Mistake: Using a pot that’s too small. Fix: The pasta needs space to be submerged; a 4-quart pot or large, deep skillet is ideal to prevent overflow and uneven cooking.
Mistake: Adding the cream while the pot is still on high heat. Fix: As noted in Step 5, always turn off the heat first to prevent the dairy from curdling and separating.
Mistake: Not stirring enough during cooking. Fix: Stir the pasta every 3-4 minutes to prevent strands from sticking together and to ensure even sauce absorption.
Mistake: Using cold stock straight from the fridge. Fix: Use warm or room-temperature stock to maintain a steady simmer when added, preventing the cooking process from stalling.
Mistake: Overcooking the pasta until mushy. Fix: Start checking for doneness at the 12-minute mark. The pasta will continue to soften slightly in the residual heat.
Mistake: Skipping the fresh basil or adding it too early. Fix: Stir in fresh herbs at the very end to preserve their bright color and delicate flavor.
Mistake: Underseasoning at the end. Fix: Cream can mute flavors. Always do a final taste and season with salt and pepper just before serving.

Storing Tips

Fridge: Cool completely, then transfer to an airtight container. It will stay fresh for 3-4 days. The sauce may thicken; add a splash of stock or water when reheating.
Freezer: For best quality, freeze in portion-sized containers for up to 3 months. Thaw overnight in the fridge. Note: Cream-based sauces can sometimes separate slightly upon thawing but are perfectly safe to eat.
Reheat: Gently warm in a saucepan over low-medium 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 an internal temperature of 165°F (74°C).

This one-pot creamy tomato pasta is a fantastic make-ahead dish. In my tests, the flavors meld and deepen after a day in the fridge, making leftovers a treat. For meal prep, divide into single-serving containers for ready-to-go lunches.

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 spaghetti and 500ml of liquid are calibrated to serve three people comfortably or four as a lighter main course. You can easily double all ingredients in a large Dutch oven to serve a crowd; just ensure the pasta remains mostly submerged in the simmering liquid.

What can I use instead of fresh basil?

If fresh basil isn’t available, you have several flavorful options. Dried basil (use 1-2 teaspoons) stirred in with the tomatoes works, though the flavor will be more muted. Fresh parsley, oregano, or a teaspoon of Italian seasoning blend are excellent alternatives. For a different profile, a handful of fresh spinach stirred in at the end adds color and nutrients.

Why is my creamy tomato pasta sauce too thin or watery?

A thin sauce usually means the liquid hasn’t reduced enough during cooking. The solution is to continue simmering the pasta uncovered for a few more minutes, stirring frequently, until the excess liquid evaporates and the sauce clings to the strands. To prevent this, ensure you’re using a wide pan for better evaporation and avoid adding extra stock beyond the 500ml specified.
