Preheat your oven to 425°F.
Peel and cube the sweet potato into uniform pieces. Toss them with half the olive oil, a pinch of salt, and a dash of black pepper. Spread evenly on a baking sheet.
Cut broccoli into florets, drizzle with a little olive oil, and season lightly with salt and pepper. Place on the baking sheet alongside the sweet potatoes.
Roast the sweet potatoes and broccoli in the oven for about 20-25 minutes, or until tender and slightly caramelized.
Meanwhile, pat dry the chicken breast and season both sides with salt and pepper.
Heat a skillet over medium heat with a drizzle of olive oil. Add the chicken breast and cook for approximately 5-6 minutes per side, or until golden and fully cooked.
In the same skillet, reduce heat to low. Add minced garlic (from 2 cloves) and sauté until fragrant, about 30 seconds.
Pour in the heavy cream and stir, allowing it to warm and blend with the garlic for a creamy sauce. Adjust seasoning with salt and pepper if needed.
Plate the chicken breast and top with the creamy garlic sauce. Serve with a generous portion of roasted sweet potatoes and broccoli on the side.
