Place the 8-oz block of feta in a zip-top bag or a shallow bowl.
In a mixing bowl, whisk together 1/3 cup extra virgin olive oil, 1/2 tsp crushed red pepper, 1 tsp grated lemon zest, 2 tsp minced garlic, 1/4 tsp black pepper, and 2 tsp dried oregano until combined.
Pour the olive oil mixture over the feta, fully coating it, then marinate at room temperature for 30 minutes or refrigerate overnight for more flavor.
Preheat the oven to 375°F (190°C).
Transfer the feta and any remaining marinade to a small ceramic or ovenproof baking dish.
Bake for about 20 minutes, until the feta is softened and slightly golden on top.
Serve warm with sliced French bread or pita chips for scooping.
