How to Make Surf & Turf Steak with Cajun Shrimp, Loaded Mashed Potatoes & Smothered Onions
- Prepare the Potatoes: Start by boiling the cubed potatoes in salted water until they are tender. Drain and return them to the pot. Add the sour cream, milk, cheddar cheese, green onions, salt, and pepper. Mash until smooth and creamy, and keep them warm.
- Cook the Onions: In a skillet, melt the butter over medium heat. Add the sliced onions along with a pinch of salt. Stir occasionally and let them cook until caramelized and golden brown, which should take about 20-25 minutes. Set aside.
- Cook the Steaks: Season your ribeye steaks with salt and pepper. In a skillet, heat olive oil over medium-high heat. Add the steaks and cook to your desired doneness, about 4-5 minutes per side for medium-rare. Once done, remove from the skillet and let them rest.
- Prepare the Cajun Shrimp: In the same skillet, melt some butter over medium heat. Add the minced garlic and sauté until fragrant. Then, toss in the shrimp and Cajun seasoning, cooking until the shrimp are pink and opaque, which should take about 3-4 minutes.
- Serve: Plate the steaks and top them with the Cajun shrimp. Serve alongside the loaded mashed potatoes and smothered onions. Don’t forget to garnish with lemon wedges for that extra zing!
Substitutions & Additions

- If you’re a fan of veggies, toss in some steamed broccoli or asparagus on the side.
Tips for Success
- Don’t rush the onions! Allow them to caramelize slowly for the best flavor.
- Let the steaks rest after cooking to ensure they stay juicy.
- Feel free to prep the mashed potatoes ahead of time; just reheat before serving!
