Steak medallions cook quickly, making them perfect for busy evenings when you want something more special than an everyday dinner. The beef develops a caramelized crust in a hot skillet, while the creamy sauce picks up all the flavorful browned bits left behind in the pan. Fresh lemon keeps the sauce from becoming too heavy, and Parmesan adds a savory, slightly nutty finish.

Why You’ll Love These Creamy Lemon Garlic Steak Medallions
One of the best things about this recipe is how quickly it comes together. Once the steak is cut and seasoned, the entire dish can be ready in around 30 minutes.
The sauce is another highlight. Heavy cream creates a smooth, luxurious texture, while garlic and Parmesan provide rich savory flavor. Fresh lemon juice and zest balance that richness and give the finished sauce a fresh, bright character.
You can also easily customize the recipe. Add mushrooms, spinach, asparagus, sun-dried tomatoes, or extra herbs depending on what you have available.
The steak itself can be made with beef tenderloin, filet mignon, sirloin, or another tender steak cut, so you can adapt the dish to your budget.

How to Make Creamy Lemon Garlic Steak Medallions
1. Prepare the Steak
Pat the steak completely dry with paper towels.
If using beef tenderloin or a larger steak, cut it into medallions approximately 1 1/2 to 2 inches thick.
Allow the steak to sit out for about 15 to 20 minutes before cooking so it is not extremely cold when it reaches the skillet.
Season both sides with garlic powder, Italian seasoning, smoked paprika, salt, and black pepper.
Press the seasoning gently into the surface.
2. Heat the Skillet
Place a large cast-iron or heavy stainless-steel skillet over medium-high heat.
Allow it to become very hot.
Add the olive oil.
Once the oil is shimmering, the skillet is ready for the steak.
A properly heated pan is essential because steak medallions need strong heat to create a flavorful brown crust.
3. Sear the Steak Medallions
Place the medallions in the hot skillet.
Do not overcrowd the pan. If necessary, cook them in batches.
Sear for approximately 2 to 4 minutes on the first side, depending on thickness.
Avoid moving the steak too frequently. Leaving it undisturbed helps form a deep golden crust.
Flip and cook the second side for another 2 to 4 minutes.
Add 1 tablespoon butter during the final minute and spoon some of the melted butter over the steaks.
4. Check the Doneness
Use an instant-read thermometer if you want precise results.
Approximate steak temperatures include:
- Rare: 120°F to 125°F
- Medium-rare: 130°F to 135°F
- Medium: 140°F to 145°F
- Medium-well: 150°F to 155°F
For food safety, whole cuts of beef are commonly recommended to reach 145°F followed by a 3-minute rest.
Remember that the temperature may continue rising slightly while the steak rests.
Transfer the medallions to a plate and cover loosely with foil.
5. Start the Garlic Sauce
Reduce the skillet heat to medium.
Add 2 tablespoons butter.
Once melted, add the minced garlic.
Cook for approximately 30 to 45 seconds while stirring constantly.
The garlic should become fragrant but should not brown heavily.
Burned garlic can make the sauce taste bitter.
6. Deglaze the Skillet
Pour in the beef broth.
Use a wooden spoon or spatula to scrape up the browned pieces from the bottom of the skillet.
Those caramelized bits contain concentrated steak flavor and will make the sauce much richer.
Allow the broth to simmer for approximately 2 to 3 minutes so it reduces slightly.
7. Add the Cream
Reduce the heat to medium-low.
Pour in the heavy cream.
Add Dijon mustard, thyme, oregano, black pepper, and optional red pepper flakes.
Stir well.
Allow the sauce to gently simmer for approximately 3 minutes.
Avoid boiling aggressively because high heat can cause dairy-based sauces to separate.
8. Add the Parmesan
Gradually stir the freshly grated Parmesan into the cream sauce.
Add it in small amounts while continuously stirring.
Continue cooking until the cheese melts and the sauce becomes smooth and slightly thickened.
If the sauce becomes too thick, add a small splash of beef broth.
9. Add Lemon Zest and Juice
Stir in the fresh lemon zest.
Add the lemon juice gradually while stirring.
The lemon should brighten the sauce without making it overly tart.
Taste before adding more.
Fresh lemon is especially important here because bottled juice will not provide the same clean citrus flavor or aroma.
10. Return the Steak to the Skillet
Place the steak medallions back into the creamy lemon garlic sauce.
Spoon some of the sauce over each piece.
Allow them to warm gently for 30 seconds to 1 minute.
Do not continue simmering the steak for several minutes because it can quickly move beyond your preferred level of doneness.
11. Finish and Serve
Remove the skillet from the heat.
Taste the sauce and adjust with additional salt, black pepper, Parmesan, or lemon if necessary.
Sprinkle chopped parsley and fresh thyme over the top.
Finish with freshly cracked black pepper and a few thin lemon slices for presentation.
Serve immediately with plenty of sauce spooned around each steak medallion.
What to Serve With Creamy Lemon Garlic Steak Medallions
Creamy mashed potatoes are one of the best side dishes for this recipe because they absorb the rich lemon-garlic sauce beautifully.
Pasta is another excellent option. Fettuccine, linguine, tagliatelle, or penne all work well with the Parmesan cream sauce.
Rice, risotto, or creamy polenta can also create a satisfying base for the steak.
For vegetables, try roasted asparagus, broccoli, green beans, Brussels sprouts, mushrooms, or zucchini.
Garlic bread or crusty artisan bread is especially good for soaking up every last bit of the sauce.
Tips for Perfect Steak Medallions
Pat the steak dry. Surface moisture prevents proper browning.
Use a very hot skillet. This creates a deeply caramelized crust without requiring long cooking.
Do not overcrowd the pan. Too much meat causes steaming instead of searing.
Use a thermometer. It is the easiest way to avoid overcooking expensive steak.
Let the steak rest. Resting allows the juices to redistribute.
Use fresh Parmesan. Freshly grated cheese melts more smoothly.
Keep the cream sauce gentle. Avoid boiling after adding cream and Parmesan.
Add lemon slowly. You can always add more, but too much acidity can overpower the steak.
Easy Recipe Variations
Creamy Lemon Garlic Mushroom Steak
Sauté 8 ounces sliced cremini mushrooms after removing the steak.
Cook until golden before adding the garlic and broth.
Creamy Spinach Steak Medallions
Add 2 cups baby spinach to the sauce just before returning the steak.
Cook until the spinach wilts.
Spicy Lemon Garlic Steak
Increase the crushed red pepper flakes or add a small pinch of cayenne pepper.
Extra Garlic Steak Medallions
Increase the garlic to 7 or 8 cloves for a stronger garlic flavor.
Lemon Herb Steak Without Cream
Skip the heavy cream and Parmesan. Finish the pan sauce with butter, lemon juice, garlic, parsley, and thyme for a lighter version.
Storage and Reheating
Store leftover steak and sauce in an airtight container in the refrigerator for up to 3 days.
For best results, reheat gently in a skillet over low heat.
Add a splash of beef broth or cream to loosen the sauce if it has thickened in the refrigerator.
Warm only until heated through.
Avoid boiling or reheating for too long because the steak can become overcooked.
Frequently Asked Questions
What steak is best for medallions?
Beef tenderloin or filet mignon is ideal because it is exceptionally tender. Sirloin can also be used for a more affordable option.
Why did my cream sauce become grainy?
The heat may have been too high, or the Parmesan may have been added too quickly. Keep the sauce over gentle heat and add the cheese gradually.
Can I use half-and-half instead of heavy cream?
Yes, but the sauce will be thinner and more sensitive to high heat.
Can I add mushrooms?
Absolutely. Mushrooms pair beautifully with steak, garlic, cream, and lemon.
Can I make this ahead?
The sauce can be prepared ahead, but the steak tastes best when freshly seared and served immediately.
