Directions

Instructions Checklist
  • Preheat oven to 375 degrees F (190 degrees C).

    Advertisement
  • Heat olive oil in a large skillet over medium heat; cook and stir onion in the hot oil until just fragrant, 3 to 5 minutes. Add garlic and cook for about 45 seconds. Mix chicken tenders into onion mixture; cook until chicken is browned, 3 to 4 minutes per side. Transfer chicken mixture to a 9x13-inch baking dish.

  • Cover chicken mixture with spinach; pour marinara sauce over spinach layer. Cover the baking dish with aluminum foil.

  • Bake in the preheated oven until chicken is no longer pink in the center and spinach is wilted, about 30 minutes.

  • Fill a large pot with lightly salted water and bring to a rolling boil. Stir in the fettuccine, bring back to a boil, and cook pasta over medium heat until cooked through but still firm to the bite, about 8 minutes. Drain and transfer fettuccine to serving plates.

  • Top each plate with chicken-marinara mixture; garnish each serving with Parmesan cheese.

I used wheat rotini pasta because its what I had on hand. It was great. Also added fresh mushrooms to onion and garlic mix. I seasoned my chicken with Mrs Dash and I'm glad I did because it would have been bland. I substituted the marinara sauce for just diced tomatoes as I wanted a lighter dish. It was awesome. I will definitely make this dish again! Read More

"Blah." In one word. I started cooking two years ago because if you can read you can cook. I select a recipe and then use your comments because you've been doing this a lot longer than me. I added mushrooms onions kalamatra olives and Mrs. Dash seasoning on the chicken. The resuts....Boring. I need some advice. What's a terrific chicken recipe? Thanks to each one of you. You are the best. Jack from St. Louis Read More

This is even easier if you make it all in one skillet less to wash. I added in some black olives also. Read More

This was very easy and very tasty. Make sure you use a good marinara sauce with this as that is the main flavor. Read More

I made this almost exactly as written & it was very good. My whole family cleaned their plate. I didn't use quite as much onion or garlic as the recipe called for. I served with veggie pasta & no one even noticed. Very good will put in the rotation! Thanks for the recipe. Read More

4 and a half stars. I feel that salt and pepper are an option in every recipe and as one reviewer wrote most of the flavor is from the sauce so make sure you have a good one before you move on. I liked the way it came out except it was on the watery side from the spinach. I will most likely make this again but I will remove the foil half way through the bake time. Read More

This is a great start! I also added sun dried tomatoes (in oil sliced) kalamata olives sliced and Italian seasoning (basil oregano some crushed red pepper) Instead of baking it I put the spinach and tomato sauce on top and covered while leaving it on the stove top. My tomato sauce had artichoke hearts in it but if it had not I would add a small can drained then chopped. I would have added some Feta or Parmesan at the end too but I'm trying to cut back on cheese:( This was a winner and I will be making this again. Next time I may add orzo in substitute of the noodles. Read More

This is relatively fast and easy. I read the reviews and agreed that seasoning is needed on the chicken. I pounded 3 breasts (pounding is a must - makes chicken tender!) and sprinkled boths sides with a bit of salt pepper oregano and a bit of crush garlic. I let that sit for 30-45 min in the fridge. "Florentine" often means spinach and bacon so I chopped up 6 regular slices of bacon crisped them up then put those on top of cheese in the last 5 min of baking. Served with whole wheat spaghetti; it was a very nice hearty dinner. Read More

Good weeknight meal. I added salt pepper basil and oregano. Leftovers were even better reheated the next day. Read More

I removed one star because the absence of salt and spices led to a bit bland chicken. I recommend adding salt and spices to the onion-garlic mix before adding the chicken. Read More
