Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente. Reserve 1 cup of pasta water, then drain.
While pasta cooks, pat salmon dry and season with salt and pepper. Heat 1 tbsp olive oil in a large skillet over medium-high. Sear salmon 4-5 minutes per side until cooked through (internal temp 145°F). Remove, flake into pieces, and set aside.
In the same skillet, add remaining 2 tbsp olive oil. Sauté garlic for 1 minute until fragrant.
Add cherry tomatoes and cook 3-4 minutes until softened. Stir in lemon zest and juice.
Toss in spinach and wilt for 1-2 minutes.
Add cooked pasta, flaked salmon, and basil. Toss with reserved pasta water (start with 1/2 cup) to create a light sauce. Season with salt, pepper, and red pepper flakes.
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove with a splash of water to loosen the sauce. Not recommended for freezing (pasta can get mushy).
