Crockpot Tuscan Cod with Sun-Dried Tomatoes and Spinach

There’s something magical about opening your crockpot to find a restaurant-quality dinner waiting for you. The aroma hits first, creamy and savory with just a whisper of garlic and Italian herbs, and you haven’t been in the kitchen for hours. That’s exactly what happens with this Tuscan cod, and honestly, it feels like you pulled off something way harder than you actually did.

This recipe takes the easiest cooking method (the slow cooker) and pairs it with one of the most delicate proteins (white fish), and somehow they become best friends. The key is knowing the secret: low heat and respect for timing. Get those right, and you’ll have tender, flaky cod swimming in a luxurious cream sauce that tastes like it came straight from a Tuscan trattoria.

I created this dish for nights when you want something elegant but can’t spend all evening cooking. Whether you’re a busy home cook, a seafood lover looking to expand your slow cooker game, or someone who wants to prove to yourself that restaurant-quality fish is absolutely doable at home, this one’s for you.

Why You’ll Love This Recipe

Your crockpot does most of the work here, and that’s the whole point. You prep the ingredients while your coffee brews, layer everything in the pot, and let it run while you do literally anything else.

The cod stays tender instead of becoming rubbery because you’re cooking it low and slow, and the spinach goes in at the end so it doesn’t turn into mush. Plus, the cream sauce is rich enough to feel indulgent without being heavy, and it works beautifully over pasta, rice, or crusty bread.

Did you know? Sun-dried tomatoes have concentrated flavor because the drying process removes water, intensifying their taste and creating a deeper, more complex sweetness than fresh tomatoes can offer.

Here’s everything you’ll need to make this dinner shine:

• 2 pounds cod fillets (skinless, cut into 4-5 pieces)
• 1 cup heavy cream

• 4 cloves garlic (minced)
• 2 teaspoons Italian seasoning
• 1/2 teaspoon salt (adjust to taste)

Step-by-Step Instructions

Step 1: Prep Your Ingredients

Mince your garlic and chop your sun-dried tomatoes. If you’re using oil-packed tomatoes (which I always recommend), drain them first. Have your spinach measured out and ready to go in a separate bowl. This is where slow cooker cooking shines, because once everything’s prepped, you’re done with active cooking time.

Step 2: Build the Sauce

Pour the heavy cream and chicken broth into your crockpot. Whisk them together gently to combine. Add the minced garlic, sun-dried tomatoes, Italian seasoning, salt, and red pepper flakes. Stir everything together so the flavors start mingling right from the beginning.

Step 3: Add the Cod

Lay your cod fillets in a single layer on top of the sauce. You want them sitting in the liquid, not stacked on top of each other. This ensures even cooking and prevents any pieces from overcooking while others stay underdone.

Step 4: Set the Crockpot

Cover and cook on LOW for 2 to 2.5 hours. This is critical, and I cannot stress it enough, keep it on LOW. High heat will turn your delicate white fish into a watery, mushy mess in under an hour. Check at the 1 hour 45 minute mark. Your cod is done when it flakes gently with a fork and is opaque throughout.

Step 5: Add the Spinach

When you’re close to the finish line (about 20 minutes before serving), add your handfuls of spinach and stir gently. The residual heat will wilt it down, and it’ll become part of that creamy sauce instead of disappearing into nothing.

Step 6: Taste and Adjust

Before serving, do a quick taste test. Add more salt, pepper, or red pepper flakes if you like. Some people love a bigger kick of heat, others prefer it milder. This is your dinner, so make it exactly how you want it.

Serving Suggestions

Serve this beauty over something that can soak up all that creamy Tuscan sauce. Pasta is the obvious choice, and it’s always perfect. Linguine or pappardelle work beautifully, but even simple spaghetti gets the job done. If you’re keeping things lighter, serve it over fluffy white rice or creamy risotto.

My favorite move? Serve it with crusty bread for dipping, because that sauce is too good to leave in the bowl.

Pro Tips for Success

The LOW setting is everything. I know I keep saying it, but cod is delicate. High heat breaks down the proteins too fast and releases moisture, leaving you with fish that falls apart and turns watery. LOW heat cooks it gently, keeping it tender and flaky.

Don’t skip the drain step on the sun-dried tomatoes. If you use the oil straight from the jar, you’ll end up with a greasy sauce. Draining them removes excess oil while keeping their rich flavor intact.

Layer your ingredients intentionally. The sauce goes down first so the fish has something to sit in, not on top of. This prevents the bottom from burning and ensures even heat distribution.

Stir gently when adding spinach. You’re not trying to mix the entire pot. Just fold it in so it wilts and becomes part of the sauce. Your cod pieces are already tender and don’t need aggressive stirring.

Storage and Leftovers

This dish keeps beautifully in the fridge for 3 to 4 days in an airtight container. Reheat gently on the stovetop over low heat, stirring occasionally, or microwave it for about 2 minutes.

The flavors actually deepen a day or two after cooking, so don’t hesitate to make this ahead. Freeze it in portions for up to 2 months, though I’d recommend eating it within the first month for best quality.

Substitutions and Swaps

Can’t find cod? Halibut, haddock, or sea bass work beautifully here. Any mild white fish will work, as long as you respect that LOW setting.

Prefer lighter? Use half cream and half Greek yogurt stirred in at the end instead of all heavy cream. It cuts the richness while keeping the luxurious feel.

Not a spinach fan? Swap it for kale or arugula if that’s more your style. The wilting time stays the same, and the flavor is equally delicious.

Out of sun-dried tomatoes? Use diced fresh tomatoes or a combination of diced tomatoes and a touch of tomato paste for depth.

Frequently Asked Questions

Can I use frozen cod? Yes, but increase the cooking time to 2.5 to 3 hours. Make sure it’s thawed before cooking if possible, as this helps it cook more evenly.

Why is my cod falling apart? It’s either cooked too long or was cooked on HIGH. Check at 1 hour 45 minutes and remember that the LOW setting is non-negotiable for white fish.

Can I double this recipe? Absolutely. Just make sure your crockpot is large enough that everything fits comfortably in a single layer, and increase the cooking time slightly to 2.5 to 3 hours.

Is this recipe healthy? Yes. Cod is high in protein and low in fat, packed with omega-3 fatty acids, and the vegetables add fiber and nutrients. It’s a balanced, nourishing meal without feeling like deprivation.
