Ingredients
Cheesy Mashed Potatoes
- 2 lbs Yukon Gold or Russet potatoes
- 4 tablespoons unsalted butter
- ½ cup whole milk (or heavy cream for richer texture)
- 1 cup shredded cheddar cheese
- ½ teaspoon garlic powder
- Salt and black pepper to taste
- Optional: ¼ cup sour cream or cream cheese
Grilled Chicken
- 2 large chicken breasts or 4 thighs
- 2 tablespoons olive oil
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- Salt and pepper
- Optional: fresh lemon juice
Broccolini
- 1 bunch broccolini
- 1 tablespoon olive oil
- Salt and pepper
- Optional: minced garlic or red pepper flakes
Step-by-Step Instructions
1. Cook the Potatoes
- Peel and cut potatoes into evenly sized chunks
- Place in cold, salted water
- Bring to a boil and cook for 15–20 minutes until fork-tender
- Drain and let them sit briefly to release excess moisture
Tip: Letting the potatoes steam dry prevents watery mashed potatoes.
2. Make Them Creamy and Cheesy
- Mash potatoes while still hot
- Add butter first so it melts evenly
- Gradually mix in warm milk or cream
- Stir in shredded cheese until smooth and melted
- Season with garlic powder, salt, and pepper
For extra richness, fold in sour cream or cream cheese.
3. Cook the Chicken
- Pat chicken dry to help it sear properly
- Rub with olive oil and seasonings
- Heat a skillet or grill over medium-high heat
- Cook for 5–7 minutes per side until internal temperature reaches 165°F
- Let rest for 5 minutes before slicing
Pro tip: Resist flipping too often—this builds a golden crust.
4. Prepare the Broccolini
- Toss with olive oil, salt, and pepper
- Sauté or grill for 5–7 minutes until tender with slight char
- Add garlic or chili flakes at the end if desired
5. Assemble and Serve
- Spoon mashed potatoes onto the plate
- Add sliced chicken alongside or on top
- Finish with broccolini
- Optional: drizzle with pan juices or melted butter

Frequently Asked Questions
Can I make mashed potatoes ahead of time?
Yes. Store them in the fridge and reheat with added milk or butter to restore creaminess.
What potatoes are best for mashing?
Yukon Golds are ideal for their naturally buttery texture, but Russets also work well.
Can I bake the chicken instead of grilling?
Absolutely. Bake at 400°F for 20–25 minutes or until fully cooked.
How do I get extra creamy mashed potatoes?
Use warm dairy, plenty of butter, and avoid overmixing.

Not quite. Broccolini is more tender, slightly sweeter, and cooks faster.
