Ingredients

Ingredient Notes

Spaghetti Noodles – Makes a great base for Alfredo sauce. Of course, you could use fettuccine, linguine, or any other pasta that you like.

Proscuitto – Adds a nice salty crunch to the pasta. You could also use bacon or pancetta.

Frozen Peas – Frozen peas keep their texture and flavor better than canned. They also have a bit more sweetness to balance out the creaminess of the sauce and the saltiness of the prosciutto.

Heavy Cream – This is what makes Alfredo sauce so creamy! It will typically be labeled as heavy cream or heavy whipping cream.

Whole Milk – Whole milk has a higher fat content than other milk and will result in a richer sauce. You can swap it for lower-fat milk but the sauce will be thinner.

Parmesan Cheese – Provides most of the flavor in Alfredo sauce. I prefer to use an Italian Parmigiano-Reggiano but American Parmesan works great too.

Note: Avoid the pre-grated or pre-shredded parmesans. They won’t taste nearly as good and likely won’t fully melt into the milk.

Step By Step Instructions

Note: Full list of ingredients, their amounts, and instructions can be found in the recipe card below.

Step 1:

Bring a large pot of salted water to a boil. Boil the spaghetti noodles according to the package instructions for al dente pasta. Drain.

Step 2:

While the pasta is boiling, heat the olive oil over medium-high heat in a large pan or casserole dish.

Then, add the chopped prosciutto and sauté, stirring often, until it becomes crispy and the fat has rendered out. This should take about 5 minutes.

Remove from the pan to a paper towel-lined plate.

Step 3:

Peas sautéing in a pan with a wooden spoon.

Next, add the frozen peas to the hot pan and sauté for 1 to 2 minutes, just until they are heated through and have a bit of color.

Remove them from the pan and add them to the plate with the prosciutto.

Step 4:

Melted butter, minced garlic, heavy cream, milk, salt, and pepper in a pan simmering.

Turn the heat to medium. Add the butter, minced garlic, heavy cream, whole milk, salt, and black pepper to the pan. Allow the sauce to gently simmer (not boil) for 2 minutes, stirring occasionally.

Step 5:

Grated parmesan cheese added to Alfredo sauce.

Turn the heat down to low. Add the grated parmesan cheese and stir until melted and well combined.

Step 6:

Crispy prosciutto and peas added to Alfredo sauce.

Add the prosciutto and peas into the sauce.

*Tip* For presentation, I like to keep some of the crispy prosciutto and peas out to sprinkle over the top right before serving.

Step 7:

Finally, toss the drained spaghetti noodles into the sauce.

If you kept some of the peas and prosciutto out, sprinkle them over the top. Serve immediately with extra parmesan cheese and red pepper flakes.

Tips & Tricks

Just before draining the pasta, reserve 1/2 cup of pasta water. You can use this to thin out the sauce if it gets too thick or begins to separate. Just add a little pasta water at a time until the sauce is the thickness you like
Avoid bringing the sauce to a boil as this can result in the sauce separating (also known as breaking)
This recipe calls for 1 pound of pasta which should be enough for 4 large servings or 6 smaller servings

Storage & Reheating

Keep leftovers in an airtight container in the fridge for up to 4 days.

The best way to reheat the leftovers is to melt a tablespoon of butter in a pan over medium-low heat, add a 1/4 cup of heavy cream, milk, or a combination of the two, and then toss in the pasta. This will help keep the creaminess and prevent the sauce from breaking and becoming clumpy.

I don’t recommend microwaving leftovers.
