Make this creamy pomodoro sauce recipe for the cod fillet to poach in. You may use a different sauce if preferred, but this sauce is what I recommend for this recipe.
Once sauce is prepared according to the recipe instructions, bring to a medium-low simmer, not boiling.
Cut up the cod fillet into desired serving pieces. I cut mine into 6 serving sizes. Cut them to 4-6 pieces depending on the thickness and amount of desired servings.
Add the cod portions to the simmering sauce. Place a lid on top of the pan.
Allow the fish to simmer for about 10 minutes. Or until cooked through. The fish will be opaque and flaky. The internal temperature of the cod should read 145 degrees F. Use an instant read thermometer and test for doneness in the middle or the thickest portion of the fillet.
Serve this deliciously saucy fish over desired cooked pasta and sauce. Toss the pasta in the remaining sauce, place on a pretty platter, and add the cooked cod fillets on top of the pasta.
Sprinkle with more fresh parmigiano cheese or fresh herbs, if desired.
