Ingredients

Scale

Roasted Garlic Mashed Potatoes

  • 2 pounds potatoes Yukon Gold or Russet, peeled and cut into chunks
  • 1 whole head of garlic
  • ½ tsp extra-virgin olive oil
  • ½ cup unsalted butter divided
  • ½ cup Heavy Whipping Cream adjust to your preference
  • salt and pepper to taste
  • fresh herbs like chives or parsley optional

Steak Bites

  • 2 pounds sirloin steak Cut into bite sized cubes
  • 3 tbsp unsalted butter
  • 3 cloves garlic

Garlic Parmesan Sauce

  • 1 tbsp unsalted butter
  • 1 tbsp all-purpose flour
  • 1 cup Heavy Whipping Cream
  • ½ cup grated Parmesan cheese
  • ¼ tsp garlic powder
  • salt and pepper to taste

Instructions

  1. Preheat your oven to 400°F (200°C).

Roasted Garlic Mashed Potatoes

  1. Slice off the top of 1 whole head of garlic to expose the cloves. Drizzle with ½ tsp extra-virgin olive oil, wrap in aluminum foil, and roast for 35-40 minutes until soft and golden brown. After roasting, let the garlic cool slightly, then squeeze the roasted cloves out of their skins and set aside.
  2. In a large stockpot, add 6 cups of water and bring it to a boil. Add the potato chunks to the boiling water. Season the water with salt and cook the potatoes until tender, about 15-20 minutes. Once tender, drain the potatoes and return them to the pot.
  3. Add the roasted garlic, half of the butter (cut into chunks), and ½ cup Heavy Whipping Cream to the pot with the drained potatoes. Use a potato masher or electric mixer to mash the potatoes until smooth and creamy. If needed, adjust the consistency by adding more cream or milk. Melt the remaining butter and pour it over the mashed potatoes. Season with salt and pepper to taste. Garnish with fresh herbs like chives or parsley, if desired.

Steak Bites

  1. While the potatoes are boiling, heat a cast iron skillet over medium-high heat.
  2. Add 1 tbsp of butter and 3 cloves garlic to the pan.
  3. Once the butter is melted and garlic is fragrant, add 2 pounds sirloin steak bites to the skillet. Cook for 15-20 minutes, turning occasionally, until browned to your liking. Add the remaining 2 tbsp of butter to the skillet, then turn off the heat, allowing the steak to absorb the buttery garlic flavor.

Garlic Parmesan Sauce

  1. In a medium saucepan, melt 1 tbsp unsalted butter over medium heat. Add 1 tbsp all-purpose flour and whisk constantly for about 1 minute until a thick paste (roux) forms. Slowly pour in 1 cup Heavy Whipping Cream, whisking continuously to prevent lumps. Continue cooking and whisking until the sauce begins to thicken, about 3-4 minutes. Stir in ½ cup grated Parmesan cheese and ¼ tsp garlic powder. Continue stirring until the cheese is fully melted and the sauce is smooth. Taste the sauce and add salt and pepper as needed.

Notes

  • For Creamy Mashed Potatoes: Warm the milk and butter before adding them to the potatoes for a smoother texture.
  • Steak Doneness: Adjust cooking time for steak bites based on your preferred doneness—less time for rare, more for well done.
  • Thick Sauce: If the Garlic Parmesan Sauce thickens too much, you can whisk in a bit more cream to reach your desired consistency.
