Broccoli Mashed Potatoes

Cheesy broccoli mashed potatoes were inspired by my family's fondness for Irish Colcannon, the ever-popular loaded mashed potatoes with cabbage. These potatoes are a hit with everyone who tries them!
Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes
Servings: 8 servings

Ingredients 

  • 3 pounds red potatoes cut into 1-inch pieces
  • 1 tablespoon kosher salt for boiling
  • 2 pounds broccoli crowns trimmed to bite-size florets
  • ½ cup butter room temperature
  • ½ cup sour cream
  • ½ cup heavy cream, half and half, or milk
  • ¾ teaspoon granulated garlic or garlic powder
  • ¼ teaspoon onion powder
  • ¾ teaspoon kosher salt adjust to taste
  • ½ teaspoon freshly ground black pepper adjust to taste
  • cup freshly shredded cheddar cheese divided
  • 1 tablespoon fresh Italian parsley chopped

Instructions

  • Preheat oven to 350°F. Place the potatoes in a large pot and cover with water. Bring to a boil. Add 1 tablespoon of salt and stir to dissolve. Boil for 10-12 minutes, until you are able to easily pierce the potatoes with a fork. Take care not to overcook.
  • While the potatoes are boiling, steam or roast the broccoli. Set aside to cool.
  • Drain the potatoes and return them to the pot. Add the butter and use a potato masher or hand mixer to mash the potatoes and incorporate the butter into the potatoes.
  • Add the sour cream, garlic, onion, salt, and pepper to the potatoes and stir to combine. Slowly add the cream to the potatoes while stirring.
  • Add the broccoli and 1 cup shredded cheese to the potatoes and stir to mix throughout. Taste and adjust salt and pepper, as desired. Top with remaining ½ cup cheese and bake at 350°F for 5-10 minutes, until melted. Serve warm.
