How to Make Creamy Tomato & Spinach Pasta with Chicken

Prep & Pound

Place chicken breasts between two sheets of parchment and pound to ¾-inch thickness with a rolling pin or meat mallet. Pat very dry; moisture is the enemy of browning. Season both sides with 1 tsp kosher salt, ½ tsp black pepper, and ½ tsp Italian seasoning.

Sear the Chicken

Heat 2 Tbsp olive oil in a 12-inch stainless or cast-iron skillet over medium-high until shimmering. Lay chicken in gently; it should sizzle loudly. Cook 4 minutes without nudging—golden fond equals flavor. Flip, reduce heat to medium, and cook 3–4 minutes more until internal temp hits 160 °F. Transfer to a plate to rest; juices re-absorb for maximum succulence.

Start the Pasta

Bring a large pot of water to a boil, salt it aggressively (it should taste like the sea), and cook pasta 2 minutes shy of package directions. Reserve 1½ cups starchy pasta water before draining—liquid gold for emulsifying sauce.

Build the Flavor Base

In the same skillet (don’t wipe it out!) melt 1 Tbsp butter over medium. Add diced onion and cook 3 minutes until translucent. Stir in 3 minced garlic cloves and ¼ tsp red-pepper flakes for 30 fragrant seconds.

Simmer the Tomatoes

Pour in 28 oz canned tomatoes with their juice, crushing them between your fingers. Add 1 tsp tomato paste for depth, ½ tsp sugar to balance acidity, and ½ tsp kosher salt. Simmer 10 minutes, stirring occasionally, until reduced and spoon-coating.

Make it Creamy

Reduce heat to low and stir in ¾ cup heavy cream plus ½ cup reserved pasta water. The sauce will turn a gorgeous sunset-orange. Taste and adjust salt; it should be slightly over-seasoned because the pasta will dilute it.

Slice & Return Chicken

Slice rested chicken on the bias into ½-inch strips. Any juices on the plate? Pour them right into the sauce. Nestle chicken back into the skillet; warm 1–2 minutes.

Wilt the Spinach

Add 5 oz baby spinach by the handful, folding until just wilted and vibrant green—about 45 seconds. Overcooking muddies the color.

Toss with Pasta

Add drained pasta to the skillet. Toss vigorously, adding pasta water a splash at a time until everything is glossy and coats the noodles. Finish with ¼ cup grated Parmesan and a shower of fresh basil ribbons.

Serve & Savor

Twirl into warm bowls, top with extra Parmesan and cracked pepper, and serve immediately with crusty bread to mop up every last bit of that dreamy sauce.

Expert Tips

Control the Heat

If your cream looks like it might curdle, whisk in a tablespoon of cold butter off the heat; the emulsion will stabilize instantly.

Starchy Water

The reserved pasta water contains starch that binds sauce to pasta. Reheat it briefly if it cools, so it incorporates seamlessly.

Make-Ahead Chicken

Sear chicken up to 2 days ahead; refrigerate in an airtight container and add during the warming step to save 10 minutes on busy nights.

Bright Basil

Add fresh herbs only at the end; heat dulls their chlorophyll faster than you can say “al dente.”

Double the Sauce

This sauce freezes beautifully. Double the tomato-cream base, cool, and freeze flat in zip bags for up to 3 months.

Low-Light Option

Swap spinach for kale ribbons; massage with ½ tsp salt first to tenderize, then proceed with wilting.

Variations to Try

Sun-Dried Tomato & Basil

Replace canned tomatoes with 1 cup chopped oil-packed sun-dried tomatoes plus 1 pint cherry tomatoes for pops of sweetness.
Seafood Spinach Alfredo

Skip chicken; sear 1 lb large shrimp or scallops 1 minute per side, then proceed with sauce.
Spicy Vodka Sauce

Deglaze the onion with ¼ cup vodka before adding tomatoes; the alcohol cooks off and sharpens the fruitiness.
Vegan Creamy Tomato

Use coconut milk, swap chicken for pan-seared tofu, and finish with nutritional yeast instead of Parmesan.
Mushroom Lover

Add 8 oz sliced cremini mushrooms to the skillet after searing chicken; sauté until golden before onion step.
Lemony Spring Version

Stir in 1 tsp finely grated lemon zest and 2 Tbsp juice with the cream for a bright, lighter profile.
