What to serve with easy chicken and mushroom pasta?

Pasta always goes great along a green salad with a light dressing.

Vegetables in general, such as fresh or roasted vegetables also pair well.

Of course, we all love bread. Dinner rolls, breadsticks or crusty artisan bread will all work well too.

Sometimes I like to have a small bowl of light soup with this dish as well, such as Slow Cooker Carrot Soup or Slow Cooker Cream of Asparagus Soup.

Variations for mushroom alfredo

Mushroom spinach pasta– Add some fresh, roughly chopped spinach at the end and mix it in to make for a bit of added nutrition. If you are like me, adding spinach to anything makes me feel good because it’s healthy.

Bacon mushroom pasta– Adding a little bacon to almost any dish is a win. The flavor it brings to the table is irresistible. I like to sprinkle some precooked, crumbled bacon on top at the end.

Use other types of pastas– I used spaghetti noodles for this recipe, but you can use any of your favorite pastas. Some that would work well include linguine or fettuccine.

Use other mushrooms– White mushrooms are my favorite for this recipe, but there are many different options you can use, such as portobello, cremini, or shiitake.

Add tomatoes– Sun-dried tomatoes, roughly chopped, would be the best, because they add a nice texture and flavor without adding too much moisture to the sauce.

Tips and Techniques for cheesy mushroom spaghetti 

Mushrooms must be sautéed first- Because they release too much water during cooking and will thin out the sauce. Besides, the sautéing process adds flavor!

Pasta must be boiled and drained before being mixed in– Otherwise you will have a very soupy pasta sauce! You want to drain the pasta thoroughly before mixing it in with the other ingredients so that the sauce has a nice consistency.

Boil pasta in salted water– Because this will add to the overall flavor of the dish.

Use freshly grated/shredded parmesan cheese– Because it doesn’t have a chalky or grainy texture like the powdery kind you get at the store.

How to thicken pasta sauce? Use a cornstarch slurry that you whisk in slowly to the sauce at the end. Let it simmer uncovered while stirring occasionally and the sauce will thicken nicely.

How to make pasta sauce thinner? You can add more liquid, such as milk, water, or broth a little at a time until it reaches your desired consistency.

Storage for mushroom fettuccine

Fridge- Store in a sealed container in the fridge for up to 2 days. Pasta will absorb a lot of the sauce overnight so you will need to add a splash of broth, milk, or water to bring it back to the same consistency when reheating.

Freezer- This cannot be frozen. It does not thaw well and the texture of pasta changes dramatically.
