Making the Lemon Basil Pesto Spaghetti
(scroll down to the bottom of post for the full recipe)
Ingredients You Will Need
- Basil
- Lemon
- Pine nuts
- Olive oil
- Garlic
- Cherry tomatoes
- Spaghetti noodles
- Parmesan cheese
How to Make Pesto
What equipment will I need? To make pesto, you will need either a food processor or blender. We typically prefer to use a food processor since it has a wider surface area that helps break down the pesto, but either will work just fine!
Do I need pine nuts? Traditionally, pine nuts are used in pesto but we definitely understand that these are a bit of a pricier nut! Sliced almonds will work perfectly in place of the pine nuts.
How is it made? Combine basil, nuts, fresh garlic, and lemon juice in food processor or blender and blend on high speed while drizzling olive oil through top.
Stop the machine and scrape down the sides as necessary until you end up with a smooth pesto. Don’t forge to season well with salt and pepper!
How do I store it? Pesto may be stored in a container or jar in refrigerator up to 1 week.

Tips for Perfect Basil Pesto Spaghetti
- Use fresh lemon juice – fresh lemon juice is key here to a strong lemon flavor!
- Roast cherry tomatoes – roasting the cherry tomatoes brings out a ton of flavors and makes them super juicy and perfect for folding into the pasta.
- Reserve pasta cooking water – a few splashes of pasta water helps break up the sauce a bit and keeps the spaghetti saucy and creamy.
- Top spaghetti with extra Parmesan and basil – optional, but so very delicious!
Recipe Variations
This recipe is a blank canvas for many adaptations! Try these ideas…
- Add meat – crumbled sausage, cooked chicken, or meatballs would be great meaty additions.
- Throw in more veggies – try sauteed mushrooms, sweet pepper, zucchini, or a handful of baby spinach.
- Change up the cheese – asiago, a few slices of fresh mozzarella, or burrata are a great way to change up the cheese game.
Storing and Reheating Pasta
This pasta stores well in the refrigerator up to 6 days.
Reheat leftovers in microwave 1-2 minutes, stirring at 30 second intervals. This spaghetti is also just as delicious cold!

Seriously, you haven’t had even one legit summer day until you’ve made this spaghetti, guys.
It’s got literally ALL the flavors of summer packed into it with the fresh basil and lemon, the juicy cherry tomatoes, and the rich Parmesan cheese.
We love this spaghetti alongside grilled chicken or fish but it’s MORE than worthy to stand alone as a lighter, vegetarian dinner or lunch!
