Cut the broccoli heads into small florets. Rinse well under cold water and drain.
Step 2: Cook the Broccoli
Place the broccoli in a large skillet. Add 3 cups of water, salt, and black pepper.
Bring the water to a boil over high heat. Once boiling, cover the skillet with a lid and cook for 6–8 minutes, or until the broccoli is tender but still bright green.
Step 3: Drain the Water
Carefully drain the water from the skillet. Return the broccoli to the stove over low heat.
Step 4: Add Butter and Garlic
Add 6 tablespoons of butter to the broccoli. Let it melt completely. Stir well so the broccoli is coated evenly.
Add minced garlic and cook for about 1 minute, stirring gently.
Step 5: Add Parmesan Cheese
Sprinkle grated Parmesan cheese over the broccoli. Mix well until everything is coated in cheesy garlic butter.
Remove from heat and set aside.
Make the Lemon Butter Sauce
In a small saucepan, melt ⅓ cup butter over low heat.
Add grated garlic and sea salt. Cook for about 1 minute.
Remove from heat.
Stir in fresh lemon juice.
Add black pepper to taste.
Drizzle the warm lemon butter sauce over the broccoli. Garnish with parsley and red pepper flakes if desired.
Serve immediately and enjoy.
