- In the steak pan, melt 1 tbsp butter; add half the garlic paste (more to taste) and cook 1 minute.

FAQs
Can I Use a Different Cut of Steak?
Yes—flank, skirt, or hanger steak works well. Just adjust cooking time based on thickness.
What’s the Best Way to Reheat the Steak?
Use a skillet over medium-low heat or a warm oven, covered in foil to preserve juiciness.
Can I Prepare This Ahead?
Yes—roast garlic earlier in the day and prepare the mashed potatoes ahead to save time before serving.
Can I Skip the Demi-Glace?
You can, but it adds depth and richness. A red wine pan sauce or reduced broth can be good substitutes.
How Do I Get the Potatoes Extra Creamy?
Use warm cooking liquid and hot butter. The added liquid helps achieve ultra-smooth texture.
Is there a Dairy-Free Option?
Replace sour cream with coconut cream and use dairy-free demi‑glace or mushroom-based gravy.
What Temperature Should the Steak Be Cooked To?
Medium-rare to medium (130–140°F) retains tenderness; adjust to your preference.
Why Roast the Garlic Instead of Using Raw?
Roasting mellows garlic’s bite and adds sweet, caramelized complexity to the sauce.
Can I Make This Meal Vegetarian?
Yes—skip steak and demi-glace. Swap roasted mushrooms instead and use a vegetable reduction sauce.
What Wine Pairs Best with This Dish?
A robust red like Cabernet Sauvignon or Malbec complements the garlic butter and demi-glace flavors well.

This Bavette Steak with Roasted Garlic Pan Sauce is a beautifully balanced and flavorful dish—comforting, rich, and elegant without complicated steps.
