Creamy Avocado Pasta With Roasted Tomatoes
A vibrant, low-fat vegetarian pasta for two featuring tender spaghetti tossed in a silky, no-cook sauce of blended avocado, spinach, dried basil, and low-fat Greek yogurt, finished with sweet blistered cherry tomatoes.

Ingredients
- 200 g spaghetti
- 1 ripe avocado, pitted and peeled
- 100 g fresh spinach leaves
- 1 tsp dried basil
- 2 garlic cloves, peeled
- 100 g low-fat Greek yogurt
- 200 g cherry tomatoes, left whole
- 1 tbsp olive oil
- Juice of half a lemon
- Salt and freshly ground black pepper, to taste
Instructions
Roasting The Tomatoes
- Preheat the oven to 200°C and place the cherry tomatoes on a baking tray tossed with olive oil, salt, and black pepper.
- Roast for 15 minutes until the tomatoes are soft, lightly blistered, and juicy.
Cooking The Pasta
- Bring a large pot of salted water to a rolling boil over high heat.
- Cook the spaghetti for 8 to 10 minutes until tender yet firm to the bite (al dente).
- Reserve 120 ml (1/2 cup) of the starchy pasta cooking water before draining the noodles.
Blending And Assembling
- In a blender, combine the avocado, spinach, dried basil, garlic, low-fat Greek yogurt, lemon juice, salt, and black pepper.
- Blend on high speed for 1 to 2 minutes until completely smooth, velvety, and bright green, adding a splash of the warm reserved pasta water if needed to loosen.
- Transfer the warm drained pasta to a large bowl, pour over the green sauce, and toss thoroughly for 1 minute until the noodles are evenly coated and glossy, adding extra pasta water gradually as needed.
- Divide between two plates and top immediately with the warm roasted cherry tomatoes.

Notes
Note
Crucial Tip: Never heat the avocado sauce directly in a pan. The residual heat from the freshly drained pasta is sufficient to warm the sauce through. Direct heat causes avocado to oxidize, turn dull brown, and develop a bitter taste.
- Prep time: 10 minutes
- Cook time: 15 minutes
- The lemon juice provides brightness and preserves the bright green color of the sauce.
- Toss the pasta immediately after draining while the noodles are steaming hot.
Variations
- Salmon Addition: Serve alongside a pan-seared or baked salmon fillet seasoned with salt and black pepper for extra lean protein.
- Steamed Broccoli: Fold in small steamed broccoli florets alongside the blistered cherry tomatoes for extra texture and greens.
- Zucchini Ribbons: Sauté thinly sliced zucchini ribbons in a teaspoon of olive oil and toss through the warm pasta.
- Roasted Bell Peppers: Add sliced sweet red peppers to the roasting tray with the cherry tomatoes for extra natural sweetness.
- Ricotta Enrichment: Blend two tablespoons of low-fat ricotta into the sauce alongside the yogurt for a milder, creamier finish.
Troubleshooting
- Sauce is too thick: Whisk in an extra tablespoon of warm reserved pasta cooking water until the sauce reaches a smooth, pourable consistency.
- Sauce turns dull or brown: Ensure the lemon juice is blended in thoroughly and toss the pasta immediately after blending to prevent oxidation.
- Pasta cools down too fast: Warm the serving plates with hot water prior to plating and combine the sauce with the noodles while they are steaming hot.
- Garlic flavor is too pungent: Lightly toast the unpeeled garlic cloves in a dry pan for 2 minutes before peeling and blending to mellow the sharp raw bite.
