Ingredients
For the Steak & Shrimp:
-
1 lb (450g) sirloin steak (or ribeye for extra fat), sliced into thin strips against the grain
-
12 large shrimp (about ½ lb), peeled and deveined (tails on or off)
-
1 tbsp olive oil (for steak)
-
1 tbsp unsalted butter (for shrimp)
-
2 cloves garlic, minced
-
Salt and black pepper, to taste
-
½ tsp smoked paprika (divided between steak and shrimp)
For the Cheesy Sauce & Veggies:
-
1 tbsp unsalted butter
-
½ medium yellow onion, thinly sliced
-
½ red bell pepper, thinly sliced
-
½ cup heavy cream
-
4 oz (about 1 cup) sharp cheddar cheese, freshly shredded (pre-shredded bags have anti-caking agents that ruin the sauce)
-
2 oz cream cheese, softened
-
½ tsp xanthan gum (optional, for thickening)
-
¼ tsp cayenne pepper (optional, for heat)
-
Salt and pepper, to taste
For Garnish:
-
2 tbsp fresh parsley, chopped
-
Red pepper flakes (optional)
Instructions
1. Prep the Ingredients
Before turning on the heat, ensure your steak is patted completely dry with a paper towel. Moisture is the enemy of a good sear. Slice the steak into thin strips and season generously with salt, pepper, and ¼ teaspoon of smoked paprika. Season the shrimp with the remaining paprika, salt, and pepper. Have all your veggies chopped and cheese shredded—this recipe moves fast.
2. Sear the Steak (High Intensity)
Place a large cast-iron skillet over medium-high to high heat. Add the olive oil. When the oil is shimmering (almost smoking), add the steak strips in a single layer. Do not overcrowd the pan. If necessary, work in batches.
-
Intensity Level: High
-
Time: 2–3 minutes total
Sear the steak for about 60–90 seconds per side until a deep brown crust forms. You want the steak medium-rare to medium at this stage, as it will warm through later. Remove the steak from the skillet and set aside on a plate.
3. Cook the Shrimp (Medium Intensity)
Lower the heat to medium. Add 1 tablespoon of butter to the same hot skillet. Once melted, add the shrimp and minced garlic.
-
Intensity Level: Medium
-
Time: 2–3 minutes
Sauté for 1–2 minutes per side until the shrimp turn pink and opaque. Be careful not to overcook them, or they will become rubbery. Remove the shrimp and set them aside with the steak.
4. Sauté the Vegetables (Low-Medium Intensity)
In the same skillet, add the remaining 1 tablespoon of butter. Toss in the sliced onion and bell pepper.
-
Intensity Level: Low-Medium
-
Time: 3–4 minutes
Sauté until the onions are translucent and the peppers begin to blister and soften slightly. This deglazes the pan, scraping up the flavorful browned bits (fond) left behind by the steak and shrimp.
5. Create the Keto Cheese Sauce (Medium Intensity)
Reduce the heat to low. Pour in the heavy cream. Stir continuously, scraping the bottom of the pan to incorporate all those delicious browned bits.
-
Intensity Level: Medium (requires constant whisking)
-
Time: 2–3 minutes
Add the cream cheese and stir until it melts into the cream. If you are using xanthan gum, sprinkle it in now to thicken the sauce without adding flour. Slowly add the shredded sharp cheddar cheese, a handful at a time, stirring constantly until you have a smooth, velvety sauce. Season with cayenne, salt, and pepper to taste.
6. Assemble the Skillet Bowl (Low Intensity)
Return the cooked steak and shrimp (along with any juices collected on the plate) to the skillet.
-
Intensity Level: Low
-
Time: 1 minute
Gently toss everything together until the meat and shrimp are coated in the cheesy sauce and warmed through. Turn off the heat.
7. Garnish and Serve
Sprinkle generously with fresh chopped parsley and red pepper flakes. Serve immediately directly from the skillet or divide into bowls.
Chef’s Tips for Success
-
Don’t Skimp on the Sear: High heat is crucial for the steak. If the pan isn’t hot enough, the steak will steam rather than sear, resulting in a grey, flavorless crust.
-
Shred Your Own Cheese: Pre-shredded cheese is coated in potato starch and cellulose. It will make your sauce grainy rather than smooth. Always shred from a block for keto sauces.
-
Xanthan Gum Alternative: If you don’t have xanthan gum, you can let the sauce simmer for an extra 3–5 minutes to reduce and thicken naturally. The cream cheese also provides some body.
Variations & Substitutions
-
Different Protein: Not a fan of shrimp? Use scallops or diced chicken breast. Not a steak lover? Sliced pork tenderloin works beautifully.
-
Spice Level: For a smoky chipotle flavor, add 1 tablespoon of chopped chipotle peppers in adobo sauce to the cheese sauce.
-
Vegetarian Option: Omit the steak and shrimp. Double the bell peppers and add 8 oz of sautéed portobello mushrooms for a hearty, umami-packed version.
Storage & Reheating
-
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
-
Reheating: Keto cheese sauces can separate in the microwave. Reheat gently in a skillet over low heat, adding a splash of heavy cream or water to bring the sauce back together. Stir frequently until warmed through.
