Keto Alfredo Sauce
Making this homemade low-carb alfredo sauce really isn’t that much more difficult than opening a jar of premade sauce. With just a few extra steps, you can feel good about eating this and serving it to your family.
This recipe is perfect for anyone that loves Italian foods. If that’s you, then you might also like this recipe for keto baked spaghetti too! Pasta is no longer off-limits on the keto diet!
Homemade sauce is always healthier than store-bought. You always know what’s in it when you make it yourself. Even the healthiest store-bought sauces will have something that you’ll wish you could change. I’ve even been known to doctor up jarred alfredo sauce because it just tasted too bland.
Feel free to make changes to this recipe to suit your tastes. Use more garlic or add some red pepper flakes. Then, let me know in the comments what changes you made – I’d love to hear them.
Roasted Garlic Alfredo Sauce
Have you ever roasted garlic before? If not, let this be your sign that you should try it. When you roast the garlic, you will unlock some of the most amazing and deepest flavors from the garlic. It really enhances the sauce in a huge way!
Roasting garlic is pretty simple. Just slice the top off the head of garlic and rub the entire thing with olive oil. Then, wrap it in aluminum foil and bake it. When it’s done, the garlic will easily slide out of the husk and it’s really tender and easy to mash.
This is the secret to my incredible alfredo sauce. It changes the entire recipe.
Best Keto Noodles
For this recipe, I used my favorite type of low-carb noodles – Palmini noodles. They are made from hearts of palm and are incredibly high in fiber. They have so much fiber in them that it makes the net carbs really low.
Feel free to use your favorite type of keto-friendly pasta in this recipe. Try it with zoodles, spaghetti squash, or even Wonder noodles.
Easy Low-Carb Alfredo Sauce
This alfredo sauce is so easy to make that I suggest enjoying it fresh instead of trying to keep leftovers. If you want to store leftovers, the alfredo sauce will be fresh for up to 3 days if you keep it in an airtight container in the refrigerator.
It will solidify a bit, so reheat it on the stove and add more heavy whipping cream if it is still too thick.
Alfredo Dinner Ideas
This is a very simple recipe that you can build upon. I just made a delicious alfredo sauce and poured it on top of my favorite Palmini noodles. Add some spinach or kale to make it even more nutritious.
For protein, throw in some unglazed ham, shredded rotisserie chicken, or cooked shrimp. This alfredo dinner will also taste delicious with some mushrooms and broccoli mixed in as well. Then, all you need is some keto garlic knots and your favorite copycat Olive Garden salad – and you have an Italian feast that will feed an entire family!
