Ingredients

- Garlic cloves, minced
- Plant-based milk (unsweetened—oat, soy, cashew or The Alt)

- Salt and freshly cracked black pepper
See the recipe notes below for exact quantities and tips on adjusting the sauce thickness.
Instructions
Make the sauce and finish with parsley.
- Cook the pasta
Bring a large pot of generously salted water to a rapid boil. Add the fettuccine and cook until al dente (usually 8–10 minutes). Reserve about ½ cup of the starchy pasta water before draining—it’s handy for adjusting sauce consistency. - Create the garlic-butter base
In a large skillet over medium heat, melt the vegan butter. Add the minced garlic and sauté 4–5 minutes until fragrant and lightly golden—avoid burning the garlic to keep the sauce sweet rather than bitter. - Add the milk and slurry
Reduce heat to low and pour in the plant-based milk. Whisk a flour slurry (all-purpose flour mixed with water) until smooth and stir it into the milk off the heat to prevent lumps. Return to medium-low and bring to a gentle simmer so the sauce thickens. Add more slurry a little at a time if you prefer a thicker texture. - Season the sauce
Stir in garlic powder, salt, and black pepper to taste. Simmer on low for 4–5 minutes, stirring often, until the sauce becomes velvety and coats the back of a spoon. - Toss with pasta
Add the drained fettuccine directly into the sauce and toss to coat evenly. If the sauce feels too tight, add a splash of the reserved pasta water to loosen it and help it cling to the noodles. - Finish and serve
Remove from heat and stir in the vegan parmesan and chopped parsley. Taste and adjust seasoning. Plate immediately and finish with cracked black pepper and an extra sprinkle of parmesan if desired. Serve hot for best texture and flavor.
Tip: For a richer mouthfeel, choose a creamier unsweetened milk such as oat or cashew. If you want more depth, a small pinch of nutritional yeast adds a savory, cheesy note.

Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stove with a splash of plant-based milk to revive the sauce, stirring frequently.

Top tips
- Use unsweetened milk – Always choose unsweetened, unflavored plant milk to keep the sauce savory.
- Whisk the slurry – Mix flour and water thoroughly before adding to avoid lumps and ensure a silky sauce.
- Simmer gently – Low, steady heat helps the sauce thicken without separating or scorching.
FAQs
My sauce is too thin—how do I fix it?
Mix a small additional slurry (for example, 1 tsp flour + 2 tbsp water), whisk until smooth, then stir into the simmering sauce and cook for a few minutes until it thickens.
What plant-based milk works best for Alfredo?
Neutral, creamy unsweetened milks like oat, soy, or cashew give the best texture and flavor for a savory Alfredo sauce.
Can I make the sauce ahead of time?
