What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying creamy texture without any fuss. Most are pantry staples, and if you’re missing any, there are easy swaps to keep you cooking.

• Spaghetti: 8 ounces (225 grams) – classic long pasta works best; I prefer Barilla for consistent results.
• Olive oil: 2 tablespoons – adds richness and helps sauté aromatics.
• Garlic: 3 cloves, minced – for that unmistakable savory punch.
• Yellow onion: 1 medium, finely chopped – builds the flavor base.
• Chicken broth: 4 cups (950 ml) – adds depth; vegetable broth works perfectly for a vegetarian version.
• Heavy cream: 1 cup (240 ml) – brings the luscious creaminess; you can swap for half-and-half if you want it lighter.
• Parmesan cheese: 1 cup, freshly grated – the star for that cheesy, tangy finish.
• Salt and black pepper: to taste – simple but essential seasoning.
• Red pepper flakes: ¼ teaspoon (optional) – adds a subtle kick if you’re feeling adventurous.
• Fresh parsley: chopped, for garnish – brightens the dish with a pop of color.

Pro tip: For a gluten-free option, swap the spaghetti for gluten-free pasta of your choice. And if you want to sneak in some veggies, toss in baby spinach or cherry tomatoes during the last few minutes of cooking.

Equipment Needed

• Large deep skillet or wide saucepan: A 12-inch (30 cm) pan with a lid works great for cooking the pasta and sauce together.
• Wooden spoon or silicone spatula: For stirring without scratching your pan.
• Measuring cups and spoons: To keep your ingredient ratios spot on.
• Sharp knife and cutting board: For prepping garlic and onions.
• Grater: Freshly grate your Parmesan for best flavor and texture.

If you don’t have a lid for your pan, a large baking sheet can work as a cover to help the pasta cook evenly. I’ve used both, and while a proper lid is ideal, the baking sheet trick is a handy budget-friendly option. Also, keeping your knife sharp makes chopping garlic and onions way easier—and safer, honestly.

Preparation Method

1. Heat the olive oil: In your large deep skillet over medium heat, add 2 tablespoons of olive oil. It should shimmer but not smoke (about 1-2 minutes).
2. Sauté aromatics: Toss in the minced garlic and chopped onion. Cook for 3-4 minutes, stirring often, until the onions are translucent and fragrant. Watch closely—burnt garlic is a no-go!
3. Add the spaghetti: Break the 8 ounces (225 grams) spaghetti in half (for easier stirring) and add them directly to the skillet, spreading them evenly over the onions and garlic.
4. Pour in the broth: Slowly add 4 cups (950 ml) of chicken broth, ensuring the pasta is mostly submerged. If not, add a splash more broth or water. This is key so your pasta cooks perfectly.
5. Bring to a boil and simmer: Increase heat to high and bring the mixture to a boil. Once boiling, reduce heat to medium-low, cover with a lid or baking sheet, and simmer for 12-15 minutes. Stir occasionally to prevent sticking and check pasta doneness.
6. Stir in cream and cheese: When pasta is tender and most liquid absorbed, pour in 1 cup (240 ml) heavy cream and stir to combine. Then add 1 cup freshly grated Parmesan cheese, stirring until the sauce turns silky and creamy. Season with salt, black pepper, and red pepper flakes (if using).
7. Final simmer: Let it cook uncovered for 2-3 minutes to thicken the sauce slightly. Watch for the sauce clinging beautifully to the pasta—that’s your cue!
8. Serve: Garnish with chopped fresh parsley and serve immediately. The creamy spaghetti is best enjoyed while warm and fresh.

Note: If your sauce gets too thick, add a splash of broth or cream to loosen it up. If too thin, keep simmering gently, stirring, until it reaches your desired consistency.

Cooking Tips & Techniques

Let’s face it—getting pasta creamy without ending up with a sticky mess can be tricky. Here’s what I’ve learned to keep this recipe foolproof:

• Don’t overcrowd your pot: Pick a pan big enough to hold the pasta and liquid comfortably. Trying to cram everything in a small pan leads to uneven cooking.
• Break pasta in half: This simple trick helps the strands cook evenly and makes stirring easier.
• Keep stirring: Especially during simmering, stir every few minutes to prevent pasta from sticking to the bottom and ensure the sauce thickens evenly.
• Use freshly grated Parmesan: Pre-grated cheese won’t melt as smoothly, and you’ll miss out on that rich, nutty flavor.
• Watch the liquid levels: Pasta soaks up liquid as it cooks, but keep an eye so it doesn’t dry out. Add broth a little at a time if needed.
• Patience with simmering: Resist the urge to crank the heat—it’ll make the pasta mushy or sauce separate. Medium-low heat is your friend.

From personal experience, I once forgot to stir regularly and ended up scraping a crispy burnt patch off the bottom (lesson learned!). Now, I keep a close eye and a wooden spoon handy. Also, multitasking by prepping garnish or setting the table while the pasta simmers saves a ton of time.

Variations & Adaptations

Want to switch things up? This recipe is super flexible and welcomes your personal twists:

• Vegetarian version: Use vegetable broth instead of chicken broth. Add sautéed mushrooms or spinach for extra flavor and nutrition.
• Spicy kick: Double the red pepper flakes or toss in a dash of hot sauce for those who like it fiery.
• Protein boost: Stir in cooked shredded chicken, crispy bacon bits, or cooked sausage slices right before serving.
• Dairy-free option: Swap heavy cream for coconut cream and use a dairy-free Parmesan-style cheese alternative.
• Seasonal veggies: Add chopped sun-dried tomatoes, roasted red peppers, or fresh peas during the last few minutes of cooking for color and crunch.

One variation I tried recently was adding a teaspoon of smoked paprika with the garlic and onion—it gave the dish a subtle smoky depth that my family couldn’t stop talking about. Feel free to get creative and make this one-pot creamy spaghetti truly your own.

Serving & Storage Suggestions

This creamy spaghetti dinner is best served hot, straight from the stove, garnished with fresh parsley to brighten the plate. Pair it with a crisp green salad or steamed veggies to balance the richness. For drinks, a chilled glass of white wine or sparkling water with lemon complements the creamy sauce nicely.

If you have leftovers (which is rare!), store them in an airtight container in the fridge for up to 3 days. To reheat, gently warm in a skillet over low heat, adding a splash of broth or cream to loosen the sauce. Microwave works too, but stir halfway through to heat evenly.

Fun fact: the flavors develop even more after resting overnight, making this dish just as delicious (if not better) the next day. So, if you’re meal prepping, this one-pot creamy spaghetti dinner has your back.
