Ingredients for oat milk Alfredo sauce displayed on a marble countertop including bowls of oat milk, lemon juice, minced garlic, nutritional yeast, tapioca flour, oregano, olive oil, and salt.

Gluten-Free Pasta: I used Barilla gluten-free spaghetti for this recipe, but feel free to use your favorite gluten-free pasta. I recommend fettuccini or our new favorite gluten-free gnocchi.
Oat Milk: Oat milk makes a great base for any dairy-free pasta sauce. It adds a creamy texture without an overwhelming flavor. It also thickens nicely without clumping. I used Earth's Own but feel free to use whatever brand you have.
Lemon Juice: My secret ingredient, adding lemon will brighten and balance out your Alfredo sauce with oat milk and is another must in this recipe.
Tapioca Flour (or corn starch): Tapioca helps thicken our dairy-free Alfredo sauce to that perfect Alfredo consistency. I find tapioca flour works best for a smooth, non-grainy texture.
Nutritional Yeast: In my opinion this is a must addition for any dairy-free alfredo sauce. It provides that cheesy flavor and adds depth to this sauce.
Olive Oil: I used extra virgin olive oil, which is Ideal for sautéing garlic. If you need an oil-free version, feel free to use coconut oil, veggie broth, or water.
Fresh Garlic Cloves: The heart of any great Alfredo, garlic adds a punch of flavor that's both aromatic and irresistible.
Oregano: I like to add in some oregano for its subtle herby flavor that complements the garlic. If your kids are adverse to anything green you can skip this ingredient.
Salt: Just enough to enhance the flavors of the sauce.

👩🏽‍🍳Instructions for making creamy vegetarian pasta

Step 1: Cook Pasta

Start by cooking your pasta according to the package instructions. While it cooks you start making the sauce. Set a timer so you don't overcook your pasta.

Step 2: Saute Your Garlic

In a medium saucepan or pot, warm the olive oil over low heat. Then add the minced garlic and sauté until it's fragrant and golden – but not brown.

Step 3: Add OAt Milk and Seasoning

Gradually pour in the oat milk while continuously stirring, then add in the garlic salt, oregano, and nutritional yeast. Stir until well combined.

Step 4: Prepare Tapioca flour

In a small bowl, mix the tapioca flour with a bit of cold water until fully dissolved

Step 5: Thicken Dairy-Free Alfredo Sauce

Slowly add the tapioca mixture in to the pot. Keep stirring until the sauce begins to thicken. If it's too thick, gradually add the reserved pasta water until you reach your desired consistency.

Step 5: Combine and Serve

Finally, stir in the lemon juice and then add the cooked pasta to the creamy alfredo sauce, tossing gently until each strand is beautifully coated. This is your moment to adjust the seasoning, adding a bit more salt or lemon juice as needed.

💡Recipe Tip for Creamy Alfredo

Prevent Lumps: Mix tapioca flour with cold water before adding it to the sauce to avoid lumps and achieve a smooth texture.
Use Gentle Heat: Cook the sauce on low to prevent separation and maintain a creamy consistency.
Flavor Depth: Use nutritional yeast for a cheesy flavor and lemon juice for freshness. Adjust these to taste.
Fresh Herbs: If possible, garnish with fresh herbs like parsley or basil to enhance flavor and appearance.
Adjusting Thickness: If your cream sauce thickens too much upon cooling, gently reheat and add a bit more oat milk to thin it out.

☺️Tips for Kids: Will My Kid Eat This?

Get Them Involved – Let kids help with simple tasks like measuring oat milk or stirring the sauce. They’re more likely to try what they help make!
Start Small – Serve a little sauce alongside familiar foods, like their favorite pasta or as a veggie dip.
Keep It Familiar – Instead of calling it “dairy-free,” try “creamy pasta sauce” or give it a fun name.
Let Them Customize – Offer toppings like vegan parmesan, fresh herbs, or steamed veggies so they can make it their own.
Mix It In – Pair it with a pasta or veggie they already love—my kids always go for vegan fettuccine Alfredo!

🔁Substitutions

Oat Milk: If oat milk is unavailable, you can use other dairy-free milk, such as soy or almond milk, for a similar creamy base. Each has subtle flavor differences but maintains the creamy consistency needed for the sauce.
Tapioca Flour: Cornstarch or arrowroot powder are good alternatives if tapioca flour isn't available. Use them in the same quantity to effectively thicken the sauce.
Nutritional Yeast: If you're out of nutritional yeast but still want that cheesy flavor, you can use another dairy-free alternative. A few tablespoons of vegan parmesan cheese or dairy-free cream cheese can be a great substitute.

🧀Oat Milk Alfredo Variations

Vegan Cauliflower Alfredo Sauce: For a vegetable-packed variation, blend cooked cauliflower into your dairy-free alfredo sauce before combining it with pasta. This adds a nutritional boost and a wonderfully creamy texture without altering the base flavor profile.
Garlic Mushroom Alfredo: Sauté sliced mushrooms and extra garlic in olive oil, then mix into the finished sauce. It offers a hearty, savory twist to the classic creamy pasta sauce, perfect for mushroom lovers.
Protein-Packed Alfredo: For those looking for a hearty addition to their creamy pasta, consider folding in cooked chickpeas or sautéed chicken pieces (if you’re not adhering to a vegan diet).
Veggie-Loaded Alfredo: Elevate the health factor by mixing in your favorite steamed vegetables with your vegan alfredo sauce. Broccoli, peas, lemon zest, and spinach work particularly well, adding color, vitamins, and an extra layer of flavor to the dish.

🥡Storing and Reheating

Refrigerator: Store leftover vegan Alfredo sauce in an airtight container for up to 3 days. Reheat on the stove over low heat, stirring occasionally. If it thickens, add a splash of oat milk or water to restore creaminess.
Freezer: Pour cooled dairy-free Alfredo sauce into a freezer-safe container, leaving space for expansion. Freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating: Warm your homemade Alfredo sauce over low heat to prevent separation or graininess, a common issue with non-dairy Alfredo sauces. Add oat milk as needed for a smooth, creamy texture.
