Creating Garlic Butter Chicken with Zucchini and Corn can be done easily by following these step-by-step instructions:

1. Prepare the Chicken: Season the chicken breasts with salt, pepper, and Italian seasoning if desired.
2. Melt Butter: In a large skillet over medium heat, melt 2 tablespoons of butter.
3. Cook Chicken: Add the seasoned chicken breasts to the skillet. Cook for 6-7 minutes on each side until golden brown and cooked through. Remove the chicken and set it aside.
4. Create Garlic Butter Sauce: In the same skillet, add the remaining butter. Once melted, add the minced garlic and sauté for about 1 minute, just until fragrant.
5. Add Zucchini and Corn: Stir in the sliced zucchini and corn. Cook for 4-5 minutes until the vegetables are tender.
6. Combine Chicken and Vegetables: Return the chicken breasts to the skillet. Spoon the garlic butter sauce over the top of the chicken and veggies.
7. Cook Together: Allow everything to cook together for an additional 2-3 minutes to heat through and meld the flavors.
8. Garnish and Serve: Remove from heat, garnish with fresh parsley if using, and serve immediately.

These straightforward steps will guide you in creating this flavorful and fulfilling meal quickly.
