20-Minute One-Pot Garlic Tomato Pasta 🍝✨

Prep time: 5 mins | Cook time: 15 mins | Total time: 20 mins
Servings: 2

If there’s one thing better than a delicious, restaurant-quality pasta dinner on a busy weeknight, it’s only having one single pot to clean up afterward!

This 20-Minute One-Pot Garlic Tomato Pasta is a total game-changer. Instead of boiling pasta separately and making sauce in another skillet, the pasta cooks directly in a flavorful, garlic-infused tomato broth. As the pasta starch releases during cooking, it thickens the liquid into a silky, rich, luxurious sauce—all in under 20 minutes!

🛒 Ingredients You’ll Need

• 200g (about 7 oz) Penne, Spaghetti, or your favorite short pasta
• 1 can (400g / 14 oz) Diced tomatoes (or 1.5 cups fresh cherry tomatoes, halved)
• 3–4 cloves Garlic, finely minced
• 1 small Yellow onion, thinly sliced
• 2 ½ cups Vegetable or chicken broth (or water + bouillon)
• 2 tbsp Olive oil
• 1 tsp Dried oregano or Italian seasoning
• ½ tsp Red pepper flakes (optional, for a slight warmth)
• Salt & black pepper to taste
• Garnish: Fresh basil leaves and grated Parmesan (or nutritional yeast)

🍳 Step-by-Step Instructions

1. Combine Everything in One Pot (2 mins)

In a wide skillet or deep pot, add the uncooked pasta, diced tomatoes (with their juice), minced garlic, sliced onion, dried oregano, red pepper flakes, olive oil, and a generous pinch of salt and pepper.

2. Add Broth & Bring to a Boil (3 mins)

Pour the 2 ½ cups of broth over all the ingredients. Place the pot over high heat and bring the liquid to a rolling boil.

3. Simmer & Stir (12 mins)

Once boiling, turn the heat down to medium-low to maintain a gentle simmer. Cook uncovered for about 10–12 minutes, stirring frequently with tongs or a wooden spoon so the pasta doesn't stick to the bottom.

Note: As the pasta absorbs the liquid, the remaining broth will transform into a rich, glossy sauce.

4. Finish & Serve (3 mins)

Once the pasta is al dente and the sauce has thickened to your liking, remove the pot from heat. Stir in fresh basil and a handful of grated Parmesan. Let it rest for 2 minutes—the sauce will thicken even more as it sits! Serve warm.

💡 Pro Tips for One-Pot Pasta Success: Don't walk away! Stirring frequently is key so the pasta cooks evenly and the starch creates a smooth, emulsified sauce.
