One of the best parts about this recipe is that you don’t have to remember to defrost the shrimp. In fact, the shrimp will cook to the perfect texture (not rubbery) along with the pasta. 

Before adding the pasta, quickly saute the garlic to bring its flavor to life in the sauce. Then do the same with the shrimp. Finally, when you dump in the pasta and cooking liquid, be sure not to stir. 

The shrimp should stay on the bottom of the pressure cooking pot, topped with the pasta and filled with enough liquid just to cover everything. This helps ensure that everything cooks evenly and doesn’t burn or produce too much foam. 

For extra flavor in the pasta, you can use low-sodium chicken broth. However, water will also work just fine!

Can I Use Other Pasta Shapes?

We love that the rotini soaks up a ton of sauce and flavor as it cooks. However, you can easily make Instant Pot shrimp alfredo with a different short pasta shape. 

As covered in our post about how to cook pasta in an Instant Pot, the general rule of thumb is to find the number of cooking minutes on the box, divide it in half, and subtract a minute. 

It’s best to cook the shrimp with a pasta shape that cooks at high pressure for 4 minutes, or 10 minutes according to the box. Generally speaking, other short pasta varieties work best.

Ingredient Swaps

There aren’t many ingredients in this easy shrimp alfredo pasta recipe. However, it’s also forgiving if you don’t have everything on hand. 

You can substitute the minced fresh garlic for 1 tsp garlic powder. If you do so, skip the step to saute garlic and add the powder with the shrimp in step 2. 

Parmesan cheese adds the richest flavor to shrimp alfredo. However, a blend of parm and mozzarella or pecorino romano will also work. 

For a lighter sauce, you can use whole milk instead of heavy cream

And for garnish, we love parsley. However, fresh minced basil will also work.

Ingredients

  • 2 tablespoons unsalted butter
  • 3 garlic cloves, minced
  • 3/4 pound raw frozen shrimp, peeled and deveined
  • 4 cups low-sodium chicken broth or water, divided
  • 1 teaspoon kosher salt, to taste

  2. Add the shrimp and sauté for another minute.
