Ingredient Highlights & Notes

The beauty of this one-pot wonder lies in its simplicity. You’ll use basic pantry ingredients that transform into something absolutely spectacular. The key is building layers of flavor from the very beginning, starting with aromatic vegetables and building up to that perfect, silky finish.

Ingredients:

• 1 tablespoon olive oil (use a good quality extra virgin for best flavor)
• 1 medium onion, diced (yellow or white onion works perfectly)
• 4 cloves garlic, minced (fresh is best – don’t skip this!)
• 1 teaspoon dried Italian seasoning (or use fresh herbs if you have them)
• 1/4 teaspoon red pepper flakes (optional, but adds a lovely warmth)
• 1 (14.5 oz) can diced tomatoes (fire-roasted adds extra depth)
• 3 cups low-sodium chicken broth (vegetable broth works for vegetarian version)
• 12 oz spaghetti noodles (break in half to fit your pot)
• 1/2 cup heavy cream (or half-and-half for lighter version)
• 1/2 cup freshly grated Parmesan cheese (plus extra for serving)
• 2 tablespoons fresh basil, chopped (or 2 teaspoons dried)
• Salt and black pepper to taste
• Optional: 2 cups cooked chicken, shrimp, or Italian sausage

Equipment & Tools

• Large, deep skillet or Dutch oven (at least 12-inch diameter to accommodate the pasta)
• Wooden spoon or pasta fork (for stirring without scratching)
• Sharp knife and cutting board
• Can opener
• Measuring cups and spoons
• Cheese grater (if using block Parmesan)

Instructions & Method

1. Build your flavor base (5 minutes)
Heat olive oil in your large skillet over medium heat. Add the diced onion and sauté for 3-4 minutes until it becomes fragrant and translucent. You’ll know it’s ready when your kitchen starts smelling absolutely amazing! Add the minced garlic, Italian seasoning, and red pepper flakes, stirring for another 30 seconds until the garlic is fragrant but not browned.

2. Add the tomatoes and broth (2 minutes)
Pour in the diced tomatoes with their juices and the chicken broth. Give everything a good stir and bring the mixture to a gentle boil. This is where the magic starts happening – all those flavors are beginning to meld together beautifully.

3. Add the pasta (12-15 minutes)
Break your spaghetti noodles in half and add them to the pot. Make sure they’re mostly submerged in the liquid. Bring everything back to a boil, then reduce heat to medium-low and let it simmer. Stir frequently – about every 2-3 minutes – to prevent sticking. Cook for 12-15 minutes, or until the pasta is al dente and most of the liquid has been absorbed.

4. Create the creamy finish (3-5 minutes)
Reduce heat to low and stir in the heavy cream and grated Parmesan cheese. Keep stirring gently until the cheese melts completely and creates that gorgeous, silky sauce. If you’re adding any cooked protein, fold it in now to warm through.

5. Final seasoning and garnish (1 minute)
Remove from heat and stir in the fresh basil. Taste and season with salt and pepper as needed. The sauce should coat the pasta beautifully – if it seems too thick, add a splash more broth; if too thin, let it sit for a minute to continue thickening.

Tips, Variations & Substitutions

Pro Tips:

• Don’t skip the frequent stirring – it prevents sticking and helps create that creamy texture
• If your pasta seems to be absorbing liquid too quickly, add broth 1/4 cup at a time
• Let the dish rest for 2-3 minutes before serving – it continues to thicken slightly

Delicious Variations:

• Protein boost: Add cooked chicken, Italian sausage, or shrimp in the last few minutes
• Veggie-packed: Stir in fresh spinach, mushrooms, or bell peppers
• Mediterranean twist: Add sun-dried tomatoes, olives, and feta cheese
• Lighter version: Use half-and-half instead of heavy cream and reduce the cheese slightly

Smart Substitutions:

• Gluten-free: Use your favorite gluten-free pasta (may need extra liquid)
• Dairy-free: Substitute coconut milk for cream and nutritional yeast for Parmesan
• Lower carb: Try shirataki noodles or zucchini noodles (adjust cooking time)

Just like my easy beef and onion stir-fry, this one-pot wonder proves that simple ingredients can create extraordinary meals!

Frequently Asked Questions

Q: Can I use a different pasta shape?
A: Absolutely! Penne, rigatoni, or shells work wonderfully. You might need to adjust the cooking time slightly and add a bit more liquid since different shapes absorb differently.

Q: My sauce turned out too thick/thin – help!
A: Too thick? Add warm broth or pasta water a little at a time. Too thin? Let it simmer uncovered for a few more minutes, or stir in a bit more grated cheese.

Q: Can I make this ahead for a dinner party?
A: While it’s best fresh, you can make it 2-3 hours ahead and reheat gently with a splash of broth. Just don’t add the fresh basil until right before serving.

Q: What’s the secret to preventing the pasta from sticking?
A: Frequent stirring is key! Every 2-3 minutes, give it a good stir. Also, make sure you have enough liquid in the pot.

Q: Can I double this recipe?
A: Yes! Use a very large pot or Dutch oven and you may need to increase the cooking time slightly. Keep stirring frequently and add extra liquid if needed.
