Thaw the frozen spinach. Don't try just throwing it in the pan to melt it. If you need to do this quickly, throw it in a microwave safe dish with a lid loosely placed on top. Microwave for ~3 minutes. (The lid will keep the steam in and help thaw this quickly) Do not tightly close the lid it will cause a steam bomb.
Turn your oven on to 350°.
In a large skillet over medium heat, melt butter and add garlic infused oil.
Add cherry tomatoes and season with oregano, salt, pepper, and a pinch of red pepper flakes. Cook until tomatoes start to look a little "beaten up".
Stir in broth, heavy cream, Parmesan, and herbs and bring to a simmer.
Reduce heat to low and simmer until sauce is slightly reduced, about 3 minutes.
Add gnocchi and toss to coat.
Pour gnocchi into a 9”-x-13” baking pan and top with mozzarella.
Bake until gnocchi is cooked through and cheese is melty, 30 minutes.
Garnish with more herbs and squeeze lemon on top before serving.
