- Preheat oven to 350 degrees F (175 degrees C). Grease a casserole dish.
- Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water, stirring occasionally until tender yet firm to the bite, about 8 minutes. Add baby spinach to the pot in the last minute of cooking; drain.
- Melt 2 tablespoons butter in a saucepan over medium heat; cook and stir onion until translucent, about 3 minutes. Stir garlic into onion mixture and cook until fragrant, about 1 minute. Whisk 2 tablespoons pesto, flour, black pepper, and salt into onion mixture until smooth; whisk milk in gradually. Cook and stir milk mixture until slightly thickened, about 2 minutes; stir in 1 1/2 cups Cheddar cheese, 1/2 cup Parmesan cheese, and 1/2 cup Asiago cheese; remove saucepan from heat and stir until cheeses are melted, about 1 minute.
