Avocado Alfredo with Roasted Cherry Tomatoes
Creamy vegan avocado Alfredo sauce over pasta, topped with sweet roasted cherry tomatoes for a fresh, healthy twist.
Ingredients
- 12 oz (340g) fettuccine or spaghetti (or pasta of choice)
- 3 large ripe avocados, pitted and scooped
- 2-3 cloves garlic, peeled
- Juice of 1 large lemon (about 3-4 Tbsp)
- 3 Tbsp nutritional yeast
- 2-3 Tbsp extra virgin olive oil
- Salt and black pepper, to taste
- 1-1.5 pints (about 3-4 cups) cherry tomatoes, halved
- 2 Tbsp olive oil (for roasting)
- Optional: fresh basil or parsley for garnish, red pepper flakes
Instructions
- Get that oven going! Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper—this makes cleanup a breeze and helps the tomatoes roast evenly without sticking.
- Roast those gorgeous tomatoes. Toss the halved cherry tomatoes with 2 Tbsp olive oil, a generous pinch of salt, and black pepper. Spread them cut-side up on the baking sheet and pop them in the oven for 20-25 minutes until blistered, juicy, and slightly caramelized. They'll smell incredible!
- Boil the pasta water like a pro. While the tomatoes roast, bring a large pot of salted water to a rolling boil. This is your chance to season the pasta itself—don't skimp on the salt!
- Cook the pasta perfectly. Add your fettuccine or spaghetti and cook according to package directions until al dente (tender but with a slight bite). Reserve about 1 cup of the starchy pasta water before draining—this liquid gold thins and emulsifies the sauce beautifully.
- Whip up the magic avocado sauce. In a blender or food processor, combine the scooped avocado flesh, garlic cloves, lemon juice, nutritional yeast, 2-3 Tbsp olive oil, salt, and pepper. Blend until ultra-smooth and creamy, like luxurious Alfredo. If it's too thick, add a splash of reserved pasta water and blend again. Taste and adjust—more lemon for zing, more salt for punch!
- Bring it all together. Drain the pasta and return it to the warm pot (off the heat). Pour in the avocado sauce and toss gently but thoroughly to coat every strand. Add splashes of reserved pasta water as needed until it's silky and glossy.
- Add the star topping. Spoon the hot roasted cherry tomatoes (with all their flavorful juices) over the sauced pasta for that burst of sweetness in every forkful.
- Garnish with love. Sprinkle with fresh chopped basil or parsley, a crack of black pepper, and optional red pepper flakes for a little kick.
- Serve it up hot! Plate immediately while everything's warm and creamy—the contrast of cool avocado richness and hot tomatoes is divine.
- Enjoy every creamy, dreamy bite. Dig in and savor how something so simple and healthy can taste this indulgent. You've just made restaurant-worthy magic at home!
Notes
This recipe is naturally vegan, dairy-free, and can be gluten-free with appropriate pasta. The sauce doesn't reheat well due to avocado's sensitivity, so plan for fresh enjoyment. If the sauce browns slightly, a stir with extra lemon revives the color.

Recipe Tips and Tricks
Use the ripest avocados possible—they should feel soft but not mushy—for the creamiest texture; if they’re slightly underripe, the sauce may turn out grainy. Blend the sauce right after making it and toss immediately with hot pasta to prevent browning (the lemon juice helps, but speed is key).
Reserve a cup of starchy pasta water to thin the sauce if it thickens too much—it’s a game-changer for silky results. Roast the tomatoes on a high heat for that blistered, concentrated flavor without overcooking them into mush.
Taste and adjust seasoning generously with salt, pepper, and extra lemon for brightness. For extra garlic punch, roast a few cloves with the tomatoes. Finally, don’t over-blend or heat the sauce after blending, as high heat can make avocado sauce bitter—keep it gentle!
Ingredients Notes
Ripe avocados are the star here, providing natural creaminess, healthy monounsaturated fats, and a mild, buttery flavor that mimics dairy Alfredo beautifully—choose Hass variety for best results, as they blend smoother. Cherry tomatoes bring juicy sweetness and vibrant color when roasted; their skins blister and caramelize, intensifying flavor without needing much prep.
Fresh garlic (both raw in the sauce and optional roasted) adds that signature pungent depth classic Alfredo relies on. Lemon juice is essential not just for tang but to prevent oxidation and keep the sauce green and fresh-tasting.
Nutritional yeast (a vegan favorite) delivers cheesy, umami notes without Parmesan—don’t skip it for that authentic Alfredo vibe. Olive oil enhances richness and helps the sauce cling to pasta. Pasta like fettuccine or spaghetti works best to hold the creamy sauce, while salt, pepper, and optional fresh basil or red pepper flakes round out the bright, balanced profile.
Variations and Substitutions
Make it gluten-free by swapping regular pasta for your favorite gluten-free variety like brown rice or chickpea pasta—they hold up well to the thick sauce. For extra protein, stir in grilled chicken, shrimp, chickpeas, or white beans after tossing.
Add greens like baby spinach, arugula, or kale right at the end for wilting in the heat and a nutrient boost. Turn up the heat with red pepper flakes, chili oil, or diced jalapeños in the sauce. For a nuttier twist, blend in a handful of soaked cashews or use cashew milk instead of pasta water for even more creaminess.
If avoiding nutritional yeast, try a sprinkle of vegan Parmesan or grated Pecorino for non-vegans. Swap lemon for lime for a brighter, more tropical note, or add fresh herbs like basil, cilantro, or parsley for pesto-like flair. For a lower-fat version, use fewer avocados and bulk with silken tofu, though it changes the flavor slightly.
Storage Options
This dish is best enjoyed fresh, as avocado sauce can brown and lose creaminess when stored. If you have leftovers, store the sauce separately from the pasta and tomatoes in an airtight container in the fridge for up to 1-2 days—press plastic wrap directly on the surface to minimize air exposure and browning.
Reheat gently over low heat with a splash of water or plant milk to loosen, but avoid microwaving on high to prevent separation. The roasted tomatoes keep well for 3-4 days refrigerated and can be added cold or warmed. Not ideal for freezing, as the avocado texture turns grainy upon thawing.
