Instructions
- 1Drizzle olive oil over salmon

Place the thawed salmon fillets into a baking dish and gently drizzle olive oil over them to ensure they are coated for seasoning.
Tip: Make sure the salmon is fully thawed and patted dry for the best oil adherence. - 2Season with salt and pepper

Sprinkle salt and freshly ground black pepper evenly across the top of the oiled salmon fillets.
Tip: Use freshly cracked black pepper for a more robust and aromatic flavor profile. - 3Chop the red onioncite: 1

Finely chop the red onion into small, uniform pieces on a wooden cutting board using a sharp knife.cite: 1
Tip: A sharp knife helps avoid bruising the onion and ensures even cooking.cite: 1 - 4Slice the garliccite: 1

Thinly slice the fresh garlic cloves on the cutting board.cite: 1
Tip: Slicing rather than mincing prevents the garlic from burning too quickly in the skillet.cite: 1 - 5Sear the salmon fillets

Heat oil in a cast iron skillet over medium-high heat, then carefully place the salmon fillets in. Sear on all four sides until nicely browned, then set aside.
Tip: Ensure the pan is properly heated before adding the salmon to prevent sticking and achieve a nice sear. - 6Sauté onion and garlic

Without cleaning the pan, add the chopped red onion and sliced garlic directly into the residual salmon oil. Sauté until fragrant and softened.
Tip: Leaving the residual oil and flavors from the salmon in the pan adds extra depth to the aromatics. - 7Add Cherry Tomatoes

Add a generous amount of fresh cherry tomatoes into the skillet along with the previously sautéed onions and garlic.
Tip: Use a mix of red and yellow cherry tomatoes for a more vibrant color palette and balanced sweetness. - 8Pour Water

Pour a small amount of water into the skillet with the tomatoes, onions, and garlic to create a light simmering liquid.
Tip: Just a splash is enough to help steam the tomatoes and form the base of the sauce. - 9Season and Add Ketchup

Add ketchup into the tomato mixture, followed by a sprinkle of salt and black pepper. Stir everything well to combine into a glossy sauce.
Tip: Ketchup adds a rich, sweet-and-tangy body to the sauce that complements the fresh tomatoes. - 10Return Salmon to Skillet

Return the seared salmon fillets to the skillet, nestling them into the simmering tomato sauce. Add a sprig of fresh thyme on top and simmer for about 3 minutes until cooked through.
Tip: Simmering the salmon in the sauce allows the fish to absorb all the savory, sweet, and tangy flavors.
