First, portion salmon into roughly ¼ lb pieces, or whatever serving size you need for your family or meal prep for the week. Remove the skin if you buy skin-on salmon. Rub salmon with ½ Tbsp olive oil and sprinkle ¼ tsp salt and ⅛ tsp black pepper. Let it sit on the counter at room temperature while you prep the tomatoes.
Seed and dice tomatoes. You could leave the seeds if you want to!***
Dice the onion.
Add remaining olive oil, butter, onion, Italian herbs, and dried basil to your skillet and sauté until onions are soft over medium-high heat, about 5 min.
Reduce heat to medium. Add minced garlic and tomatoes and stir, sauté for 2 minutes until fragrant.
Move veggies to the side and sear the salmon fillets in the middle of the pan.
Flip salmon after 2-3 minutes and cook for another 2-3 minutes. Remove the salmon from the pan and set off to the side on a plate, covered.****
Deglaze the pan with vegetable broth.
Add frozen spinach (squeezed and rinsed).
Stir in room temperature heavy cream and simmer for another 8-10 minutes.
Then add ¼ tsp salt, ⅛ tsp black pepper, grated Parmesan cheese, and minced parsley. Combine to melt the cheese into the sauce.
Add the salmon back to the skillet until warmed through. Enjoy!
*I opted for skinless salmon for this recipe, because the skin won’t crisp up in this recipe. If you buy skin on, I recommend removing the skin carefully with a sharp knife. Also, when you cut your salmon, try to aim for ¼ lb per person. Slightly less is fine if you’re serving this over pasta, rice, or mashed potatoes. **I use Better Than Bouillon brand to keep my broth costs low. The package directions require 1 tsp bouillon to 1 cup of water.***The tomato seeds can be bitter and add texture to the sauce. I like to remove them for this recipe. You can keep them in if preferred!****The USDA recommends cooking salmon to an internal temperature of 145℉.
