How to Make Creamy Keto Tuscan Cod with Spinach and Sun-Dried Tomatoes Recipe
Step 1: Prepare and Season the Cod
Start by patting the cod fillets dry with paper towels—this step is crucial for achieving a golden sear. Season both sides generously with salt and pepper. This simple seasoning lays the foundation for the cod’s delicate flavor to shine through in every bite.
Step 2: Sear the Cod Fillets
Heat the olive oil in a large skillet over medium heat. Once hot, add the cod fillets and cook each side for 3 to 4 minutes until they develop a lovely golden crust and are just cooked through. Be careful not to overcook here, as the fillets will finish cooking later in the sauce. Remove the fish and set aside to keep warm.
Step 3: Build the Sauce
In the same skillet, toss in the minced garlic and sauté briefly for 30 seconds until fragrant but not browned. Stir in the sliced sun-dried tomatoes, dried Italian seasoning, and crushed red pepper flakes, letting these ingredients release their vibrant aromas for 1 to 2 minutes.
Step 4: Create the Creamy Tuscan Base
Pour in the heavy cream and gently bring the mixture to a simmer. Once the cream is lightly bubbling, stir in the grated Parmesan cheese. Let the sauce gently thicken over 2 to 3 minutes—this step transforms simple cream into a luscious Tuscan sauce that clings beautifully to the cod.
Step 5: Add Spinach and Reintroduce the Cod
Toss in the fresh spinach and cook just until wilted, about one minute. Carefully return the seared cod fillets to the skillet and spoon the sauce generously over the top. Allow everything to simmer together for an additional 1 to 2 minutes for the flavors to meld and the fish to heat through.

Garnishes
Adding a simple garnish can elevate the presentation and flavor of this dish. A few lemon wedges served alongside provide a zesty brightness that cuts through the richness. If you want to get creative, sprinkle some freshly chopped parsley or basil for a fresh herbal note and burst of color that makes the dish feel extra special.
Side Dishes
Because this is a keto-friendly meal, pairing it thoughtfully is key. Serve over fluffy cauliflower rice or zoodles made from zucchini for a low-carb, veggie-packed accompaniment. For a heartier option, steamed asparagus or roasted Brussels sprouts with garlic butter complement the creamy sauce beautifully and keep the meal balanced.
Creative Ways to Present
For a stunning dinner presentation, serve the cod nestled in a shallow bowl surrounded by the creamy sauce and spinach. Drizzle a little extra virgin olive oil on top for shine and richness. You could also serve it plated family-style with large platters to encourage sharing—perfect for cozy gatherings where this Creamy Keto Tuscan Cod with Spinach and Sun-Dried Tomatoes Recipe is sure to impress.
Make Ahead and Storage
Storing Leftovers
If you find yourself lucky enough to have leftovers, transfer them to an airtight container and store in the refrigerator for up to 3 days. The cod and the creamy sauce maintain their flavor well, making it an easy next-day lunch or dinner option.
Freezing
While the sauce is best fresh, you can freeze cooked cod fillets separately wrapped tightly in plastic wrap and placed in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating with freshly made sauce to keep texture and flavor at their peak.
Reheating
Reheat gently on the stovetop over low heat or in the microwave at medium power to avoid drying out the fish. Stir the sauce occasionally while warming to maintain its creamy consistency. Adding a splash of cream or broth can help revive the silky texture if needed.
FAQs
Can I use other types of fish instead of cod?
Absolutely! White, flaky fish like haddock or halibut make great substitutes. Just be mindful of cooking times, since thinner fillets can cook faster and you want to avoid overcooking for the best texture.
Is this recipe suitable for people on a strict keto diet?
Yes, this dish is perfect for keto as it is low in carbs and high in healthy fats from the cream and olive oil. The spinach adds nutrients without adding significant carbs.
Can I make this recipe dairy-free?
You can try swapping heavy cream for full-fat coconut milk and use a dairy-free Parmesan alternative or nutritional yeast. The flavor profile will shift slightly but it will still be creamy and delicious.
How spicy is the dish with the crushed red pepper flakes?
The red pepper flakes are optional and provide just a subtle warmth that enhances the flavors without overpowering. Feel free to adjust the amount or omit altogether based on your spice preference.
What is the best way to serve this Creamy Keto Tuscan Cod with Spinach and Sun-Dried Tomatoes Recipe for meal prep?
For meal prep, portion the cod and sauce into individual containers and add a side of cauliflower rice or roasted vegetables. This keeps everything fresh and flavorful when reheated throughout the week.
