How to Make Oat Milk Alfredo Pasta
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Cook pasta until al dente. Reserve ¼ cup of pasta water, then drain.
Step 2: Sauté the Garlic
In a large pan, heat olive oil or vegan butter over medium heat. Add garlic and cook for about 30 seconds until fragrant.
Step 3: Make the Roux
Stir in the flour and cook for 1–2 minutes, stirring constantly. This helps thicken the sauce.
Step 4: Add the Oat Milk
Slowly pour in the oat milk while whisking to prevent lumps. Let it simmer until the sauce thickens.
Step 5: Add Flavor
Stir in nutritional yeast, salt, and pepper. Taste and adjust seasoning.
Step 6: Combine with Pasta
Add the cooked pasta to the sauce. Toss well, adding a splash of pasta water if needed for a silky consistency.
Step 7: Serve
