Ingredients You'll Need (and Why)
sirloin steak or flank steak, cut into bite-sized cubes: Sirloin offers a great balance of tenderness and beefy flavor without needing a long braising time.
unsalted butter, divided: Using unsalted butter lets you control the salt level in the pan, especially when reducing the broth.
cremini mushrooms, sliced: Cremini mushrooms have a denser texture and deeper, more robust flavor than standard white button mushrooms.
garlic, minced: Freshly minced garlic blooms in the butter to form the aromatic base of the entire cream sauce.
heavy cream: High fat content prevents the sauce from curdling when it hits the heat and creates an ultra-smooth finish.
How to Make It
Getting the Perfect Sear on the Beef
The secret to great skillet beef is moisture control and high heat. If your beef cubes are wet from the package, they will steam instead of brown. Patting them completely dry and leaving them alone in a hot pan allows a deeply flavorful crust to form.
Building Deep Flavor with Mushrooms
Mushrooms release a lot of water when they first hit the heat. We want to let that moisture evaporate so the mushrooms can actually caramelize and turn golden brown, which infuses the entire dish with a rich, savory depth.
Creating the Velvety Cream Sauce
Deglazing the pan with beef broth lifts up all those caramelized bits stuck to the bottom from searing the beef and mushrooms. Combining the broth with heavy cream and a touch of butter yields a luxurious sauce that coats the back of a spoon.
Success Tips
- Don't overcrowd the pan when searing the beef. If necessary, cook the meat in two separate batches so each piece gets direct contact with the hot surface.
- Let the mushrooms sit completely still for the first few minutes of cooking to build a deep, golden-brown crust.
- Scrape the bottom of the skillet thoroughly when adding the beef broth; those little browned bits hold an immense amount of savory flavor.
- Keep the heat at medium-low once the heavy cream is added to prevent the dairy from separating or scorching.
Variations
- Swap the beef for boneless, skinless chicken breast or thigh cubes for a creamy garlic butter chicken skillet.
- Add a handful of fresh baby spinach at the very end and let it wilt into the sauce for an extra pop of green.
Storage & Make-Ahead
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat with a splash of broth or water to thin out the sauce.
FAQ
Can I make this recipe dairy-free?
You can substitute the heavy cream with full-fat canned coconut milk, though it will impart a slight coconut flavor, or use an unsweetened plant-based heavy cream alternative. Swap the butter for olive oil or a plant-based butter substitute.
What cuts of beef work best?
Sirloin steak, ribeye, or flank steak cut into bite-sized pieces work wonderfully. Avoid tough stew meat, as it requires a long braising time and will be chewy when cooked quickly in a skillet.
What should I serve this with?
This dish is fantastic served over mashed potatoes, cauliflower mash, white rice, or egg noodles to soak up the incredible garlic butter cream sauce.
