This tart came about as a way to use up some odds-and-ends ingredients that I had been wanting to get used up. Make sure to place a baking sheet under the tart pan while baking--those tomatoes can make a bit of a mess when they burst open! They add quite a bit of juice, which can pool on top a little. I simply dabbed up extra juice with a paper towel and that worked fine. This is best served warm, on the day it's made. Garnish with additional basil, if desired.

Recipe Instructions
Step 1
Preheat the oven to 350 degrees F (175 degrees C).
Step 2
Roll out pie dough into a 12-inch circle on a lightly floured surface. Gently transfer dough to a 9-inch tart pan with a removable bottom; press to fit snugly. Trim dough so there's 1/2-inch overhang on all sides. Gently fold edges of dough under to create a slight lip of dough over the top of the pan on all sides.
Step 3
Prick the bottom of the crust several times with a fork, being sure to not puncture all the way through. Place the prepared crust into the freezer until completely chilled, at least 30 minutes.
Step 4
Meanwhile, prepare the filling. Heat olive oil in a medium skillet over medium heat. Add onion and garlic; cook until golden brown, stirring often, about 10 minutes. Remove from heat and cool to room temperature.
Step 5
Mix Gouda, basil, mayonnaise, Cheddar, Parmesan, Dijon mustard, oregano, pepper, nutmeg, and salt together in a medium bowl. Stir in the cooled onion and garlic until completely combined.
Step 6
Remove tart pan from the freezer. Gently spread the cheese mixture evenly over the bottom. Place cherry tomatoes evenly over the top and gently press down. Place tart on a large baking sheet.
Step 7
Bake in the preheated oven until the crust is golden brown, cheeses are bubbly, and most of the tomatoes have burst, 55 to 65 minutes. Cool for 20 minutes. Gently remove the tart from the pan and place on a serving platter. Serve warm.
