Pesto Pasta preparation might surprise you — it serves 8 people and takes just 15 minutes to throw together! Sound too good to be true? Well, pesto spaghetti definitely tastes too good to be true!
Fresh basil is best enjoyed in the summer through the fall, so spaghetti with pesto sauce will taste the best during the warmer months of the year.
Pasta is one of those irreplaceable weeknight wonders. It’s ready in no time, is super filling, and is totally inexpensive.
And since you can serve it with just about any vegetables, meats, or seasonings, you can make something every member of your family will enjoy!
Fresh basil and pine nuts give this pesto pasta a full, herbaceous flavor, and smooth olive oil gives it a luxurious texture.
What else? Everyone’s favorite: parmesan cheese! Throw in some garlic and just a dash of salt and pepper.
Simple, natural flavors piled onto your plate in no time. Try my Chicken Bellagio for an amazingly delicious dish.
Ingredient Notes and Substitutions
- Basil – This herb has a very strong flavor — it’s sweet and peppery at the same time, but also savory and minty.
You don’t really want to swap it out, but spinach, kale, parsley, and cilantro can sub in for a somewhat similar flavor.
Or, try using a mix for a more complex flavor in your pesto pasta!
- Pine Nuts – You can use walnuts, almonds, sunflower seeds, or hazelnuts instead. Or you can leave them out altogether if you’re not too nuts about nuts!
- Olive Oil – Extra virgin olive oil is the way to go with basil pesto pasta — actually, with almost any recipe that calls for it!
It has the most flavor out of your olive oil options.
- Spaghetti – You can actually use any pasta you like! Short, tubed pasta is a popular choice for basil pesto pasta, but really any kind will do.
Basil Pesto Pasta Recipe Tips
- Don’t rinse the noodles.
You don’t want to rinse the pasta before tossing it in the pesto. The starches help the sauce cling to the noodles, so the stickier they are, the better!
- Use freshly shredded cheese.
Grate a fresh wedge of parmesan for this pesto pasta recipe. None of that powdered stuff — fresh tastes so much better!
Fresh cheese also has fewer additives and chemicals, so it’s healthier too.
- Slow and steady wins the race!
When making the pesto, add the olive oil slowly and gradually until you get just the right thickness and consistency.
Keep in mind, you can always add more oil, but you can’t take it away!
Storing and Reheating Leftover Pesto Spaghetti
I’ll be honest — this pesto pasta recipe makes a whole lot of sauce! Like, enough to coat 4 pounds of cooked spaghetti!!!
Store leftover sauce in an airtight container in the fridge for up to 5 days, or freeze it for up to 6 months.
Of course, you can just as easily make a half batch of this basil pesto pasta recipe if that’s better for you.
Once the noodles are coated in sauce, it actually tastes better if it sits overnight in the fridge! Just like the pesto, enjoy your leftovers within 5 days.
You can reheat basil pesto pasta in the microwave in 15-second bursts until warm, or enjoy it cold.
Pesto Pasta Recipe FAQ
With Mediterranean dishes, there are plenty of vitamins in pesto to get excited about!
Basil is rich in vitamins K and A, while olive oil contains antioxidants and helps to lower blood pressure as well as inflammation.
As with all things, however, the key lies in moderation. Too much olive oil is unhealthy, so don’t overload each meal with the stuff. A serving of pesto is just enough!
I think that chicken, especially when grilled or baked, is the best protein to serve with pesto pasta.
But steak, pork, seafood — any of it goes well with the olive oil, herbs, and seasonings that are in the mix.
My favorite ways to use pesto sauce are to coat the protein with the pesto and bake it, or use the mixture as a marinade before grilling the meat. Then, serve over tender noodles!
Almost any vegetable makes a great side with pesto spaghetti. Potatoes, roasted peppers, and tomatoes are excellent choices.
Don’t forget to add some greens — my copycat Olive Garden Salad and Italian Dressing would be fabulous!
