One Pot Pasta with Salmon, Spinach, and Oven-Baked Creamy Sauce for Cozy Nights In

This one pot pasta with salmon, spinach, and an oven-baked creamy sauce is the kind of meal that makes you forget how busy the day was. It’s rich but not heavy, with the gentle tang of lemon cutting through the creaminess just right. The salmon chunks stay tender and flaky, while the spinach adds a fresh pop of green that brightens every forkful. The best part? You only dirty one pot, which somehow makes the whole experience feel less like dinner and more like a little win.

I remember the first time I tried this, the afternoon was slipping away faster than expected and I was juggling a few things at once—half the time I was staring off into space, wondering if I was supposed to stir or just wait. Somehow, the creamy sauce bubbled up perfectly in the oven while I checked emails and tried not to burn the garlic on the stove (spoiler: I didn’t, but I was close). When I finally sat down, the flavors had melded into this cozy, satisfying dish that felt like a hug. It’s not fancy, but it’s honest food that hits the spot.

• The salmon stays moist and flaky after baking, not rubbery or dry.
• The spinach wilts just enough to blend into the creamy sauce without getting lost.
• The one pot method means less time scrubbing, more time relaxing.
• It’s simple—and that’s kind of the point; no complicated steps or unusual ingredients.

If you’re worried about the sauce being too heavy, I usually find that the lemon juice brightens it up enough to keep it feeling fresh rather than overwhelming.

Instructions

Preheat the oven to 180°C (350°F).
In a large oven-safe pot or Dutch oven, heat the olive oil over medium heat.
Add the chopped onion and sauté for 3-4 minutes until translucent.
Add the minced garlic and cook for another 1 minute until fragrant.
Pour in the heavy cream and vegetable broth, stirring to combine.
Add the dried penne pasta, salt, black pepper, dried oregano, and crushed red pepper flakes. Stir well to ensure the pasta is mostly submerged in the liquid.
Bring the mixture to a gentle boil, then reduce the heat to low and simmer uncovered for 8 minutes, stirring occasionally to prevent sticking.
Remove the pot from heat and gently fold in the chopped spinach until wilted.
Place the salmon chunks evenly over the pasta mixture.
Sprinkle the grated Parmesan cheese evenly on top.
Transfer the pot to the preheated oven and bake uncovered for 15 minutes, or until the salmon is cooked through and the sauce is bubbly and slightly golden on top.
Remove from the oven and drizzle the lemon juice over the dish.
Garnish with freshly chopped dill before serving.

Cooking this in a large oven-safe pot or Dutch oven makes everything come together smoothly, and you don’t have to juggle multiple pans. Leftovers reheat well with a splash of cream or broth to loosen the sauce, so it keeps its creamy texture. I often serve this with a crisp green salad or some crusty bread for sopping up every last bit of sauce. If you want to mix it up, adding a handful of sun-dried tomatoes or swapping spinach for kale could work, though I haven’t tested those swaps extensively. Sometimes a pinch of smoked paprika adds a nice depth, but I usually keep it simple.

FAQ

Can I use frozen spinach instead of fresh? You can, but fresh spinach wilts nicer in the sauce and keeps more texture. If you use frozen, drain it well first.

What if I don’t have heavy cream? A mix of milk and a bit of butter might work, but the sauce won’t be quite as rich.

Can I swap the salmon for another fish? Sure, something like cod or trout would be fine, but cooking times might differ.

Is this dish freezer-friendly? It’s best fresh or refrigerated; freezing creamy pasta can change the texture.
