Bring a large pot of salted water to a boil. Add the green beans and cook for 3-4 minutes, until bright green and slightly tender. Remove from the water and drain. No need to do an ice bath.
In a large skillet, heat the olive oil over medium-high heat. Add the minced garlic and sauté for about 30 seconds, just until fragrant.
Add the green beans to the skillet, toss in oil and season with salt and pepper. Cook, stirring occasionally, for 5-7 minutes, until the green beans are tender. Turn of heat, add lemon zest and toss. Taste and season with additional salt, pepper and lemon juice, if desired. Serve warm.
Notes
Storage: Store any leftover green beans in an airtight container in the fridge for 3–4 days. Reheat in a skillet over medium heat until warm.
Additions: Try topping with parmesan or red pepper flakes for extra flavor.
Oil swaps: Avocado oil or butter both work great if you don’t have olive oil.
