Step 1

Add all the ingredients to a blender or food processor.

Step 2

Pulse to blend the ingredients. You can blend until completely smooth, or leave a bit of texture in the pesto to your preference.

Step 3

Reserve about 1 cup of the pasta cooking water. Combine cooked pasta, oregano pesto, and a splash of pasta water in a skillet and cook on medium-high heat until the sauce is glossy and coats the pasta.

Step 4

Add more pasta water as needed. Toss the cherry tomatoes into the skillet for the last minute of cooking. Top with parmesan cheese and enjoy!
