Alfredo Sauce - Ingredients You’ll Need
Before you start your Alfredo Sauce cooking, gather these essential ingredients:
1/2 stick of butter (4 tablespoons)
1 teaspoon of pepper
1/3 cup of minced garlic (about 4-5 cloves)
1 cup of diced onions (about 1 medium onion)
1/2 stick of butter (for roux)
4-6 tablespoons of all-purpose flour
2 cups of milk (whole milk is best for creaminess)
1-2 cups of grated Parmesan cheese (freshly grated for the best flavor)
1 1/2 teaspoons of salt
3 additional tablespoons of minced garlic (optional, for added flavor)
With these simple ingredients, you’re well on your way to crafting a delicious homemade Alfredo sauce that will enhance your pasta dishes.
Alfredo Sauce - Sauté the Vegetables
Start by sautéing the vegetables to build flavor.
In a large skillet, melt 1/2 stick (4 tablespoons) of butter over medium heat.
Add the minced garlic and diced onions along with the pepper.
Sauté these ingredients until the onions are translucent and fragrant, which usually takes about 4-5 minutes.
Once cooked, remove the sautéed onions and garlic from the skillet and set them aside. This step is crucial as it releases their flavors, making your Alfredo sauce even tastier.
Make the Roux
Next, it’s time to create the roux, which will thicken your sauce.
In the same skillet, add another 1/2 stick of butter and melt it over medium heat.
Once melted, whisk in 4-6 tablespoons of flour, mixing continuously until it thickens and resembles a smooth paste.
The roux is not just a thickening agent; it also enhances the flavor profile of your Alfredo sauce, making it more satisfying.
Combine the Ingredients
Now, let’s bring everything together for a creamy consistency.
Gradually whisk in 2 cups of milk to the roux until smooth and creamy.
Stir in 1-2 cups of Parmesan cheese until it melts and blends well with the milk.
Add in 1 1/2 teaspoons of salt and mix thoroughly.
The secret to a perfect cheese sauce is making sure it's lump-free, so keep whisking steadily. The right balance of cheese will give you a sauce that clings to your pasta beautifully.
Finish the Sauce
Now it’s time to add back the sautéed onions and garlic.
Add the sautéed mix back into the skillet with the sauce.
For a burst of added flavor, mix in 3 more tablespoons of minced garlic (if desired).
Let the sauce simmer for another minute or two until heated through and well-combined. This last step layers in even more flavor that everyone will love.
Serve Your Alfredo Sauce
Your creamy Alfredo Sauce is ready for a delicious serving!
Give everything one last stir to ensure it's blended perfectly.
Pour the sauce over your pasta immediately. Fettuccine is the classic choice, but you can use any pasta you prefer.
