Whisk the eggs, cream, and green onion in a large bowl. Season with thyme, salt, and pepper.
Add butter to an oven-proof skillet over medium heat on the stovetop. Once it melts, sauté minced garlic for 1 minute, then add the spinach and stir until it begins to wilt.
Remove the spinach from heat and combine it with the eggs in a bowl. Crumble the feta cheese with your hands into the egg mixture and stir until combined.
Add more butter to your pan, if needed, so nothing sticks. Pour the egg and spinach into the skillet. Use a fork or spatula and move the spinach around until it's distributed evenly throughout the frittata.
Bake for 15-20 minutes until the top turns golden brown and the edges set.
