The Proteins & Main Components:
- Steak – You can use your favorite cut of steak, it really doesn’t matter, and it’s more of a preference thing! We used a lean sirloin steak for this skillet, but only because we were looking to up the protein and lower the fat content a bit. Ribeye would have been ideal, but again, we were going for a dish that was slightly leaner this time!
- Shrimp – We love big, juicy shrimp for this. They should be peeled and deveined, but it’s up to you if you want to leave the tails on or not.
- Olive oil – For searing the steak at a high heat. You could use avocado oil instead if you prefer.
- Unsalted butter – This is the base of the sauce, that makes it so luscious and creamy!
- Salt & pepper – Pretty standard, make sure you season your steak and shrimp very well before skillet them off in your cast iron skillet.
- Seasonings – You can season your sauce and shrimp however you’d like, but our favorites are smoked paprika and some red pepper flakes for a little heat.
- Onion and garlic – These two are the base of any great dish, in our opinion. Feel free to substitute with onion and garlic powder if you prefer, but it’s definitely going to taste the best with fresh!
- Chopped spinach – Just to add some greenery to this dish! We like to chop ours up a little bit beforehand.
- Lemon juice and zest – This is another one of our favorite ingredients. Lemon juice and zest add some acidity, sweetness and a ton of flavor. Don’t underestimate these two!
- Broth or White Wine – To thin the sauce, and add flavor. You can go with anything you see fit here, beef, seafood, chicken or even vegetable broth. If you’re into it, use some dry white wine instead!
- Heavy whipping cream – This is where the creamy element of this sauce comes in! You will want to use heavy whipping cream so that it thickens up the best.
- Parmesan cheese – You will definitely want to use freshly grated parmesan cheese for this. Pre-shredded cheese can be convenient but parmesan especially does not melt well if pre-shredded. You want the parmesan to melt as best as it can to create the sauce.
- Parsley & parmesan cheese for garnish – When it’s time to serve, add some fresh parsley and parmesan cheese flakes on top if you want.

What Is Surf and Turf?
Surf and turf represents proteins of both the land, and the sea served together as one dish! Generally speaking, turf is often represented by red meat like steak and it’s “the land”. The surf portion is seafood, generally lobster, shrimp, prawns, or crab legs and it represents “the sea”. This dish starting gaining traction in fancy restaurants back in the 1960’s. Surf and turf (like this steak and seafood skillet) represent two gourmet tastes together.

How to Make This Steak and Seafood Skillet with Garlic Parmesan Sauce:
Heat a large skillet (at least 10.25″, we prefer a 12″ skillet) over medium high heat. Season your steaks liberally with salt and pepper. Once hot, add in olive oil, then add the steaks to the skillet. Cook about 3-4 minutes on each side, until a nice crust forms and the steaks are cooked to your liking. We like our steaks medium rare. Once cooked, set aside to rest for at least 10 minutes before slicing into the steak.
Add in some of the butter to the pan, and season the shrimp with salt, pepper, smoked paprika and some red pepper flakes if desired. Add the shrimp to the skillet, watching closing. This will take about 1-2 minutes on each side. Don’t overcook! Once shrimp are cooked through, remove from the skillet and set aside.
Add remaining butter to the skillet, along with diced onion and a pinch of salt. Cook until onion is brown and caramelized, then add in garlic and cook until fragrant, about 30 seconds. Add in the chopped spinach and cook until wilted.
After spinach has wilted, add in lemon juice, zest and chicken broth. Simmer for 2-3 minutes.
Stir in the heavy cream, along with the parmesan cheese in batches, stirring constantly until completely melted and a sauce forms. Taste and adjust seasonings to your preference.
Add the steak and shrimp back to the skillet, top with parsley and parmesan cheese.
