- First, the chicken is seasoned with paprika, salt, and pepper, and cooked in olive oil.
- Meanwhile, the Brussels sprouts are roasted in the oven until crispy.
- Then, both the cooked chicken and Brussels sprouts are combined together in a lemon garlic butter sauce seasoned with Italian seasoning and red pepper flakes.
My other popular chicken recipe that is also low-carb and keto-friendly is chicken thighs with creamy bacon mushroom thyme sauce.
What type of chicken to use?
I used skinless, boneless chicken tenderloins - they are, well, tender, and are already sliced the way I want them for this recipe. However, you can also use boneless, skinless chicken thighs or chicken breasts with equal success. Just slice them thinly.
What kind of veggies to use?
I made this with Brussels sprouts which I roasted (seasoned with olive oil, salt, and pepper) in the preheated oven at 400 F for 20 minutes. You can also use roasted asparagus, green beans, or broccoli.
How to make Lemon Garlic Butter Chicken
Start by roasting Brussels sprouts in the preheated oven at 400 F for 20 minutes.
Then, prepare the chicken. Use skinless, boneless chicken tenderloins. Slice them into thinner strips.
Generously season the chicken tenderloins with smoked paprika, salt, and pepper.
Cook chicken tenderloins in olive oil in a cast-iron skillet. After the chicken is cooked for about 5 minutes, sprinkle the chicken with Italian seasoning, crushed red chili pepper flakes, add minced garlic, freshly squeezed lemon juice, and butter. Cook for another 2 minutes or more until the chicken is cooked through but not overcooked.
Add Brussels sprouts and more butter. Stir everything together on low heat. When serving, top the chicken with chopped fresh parsley.
Helpful tips
- Prepare the Brussels sprouts. Trim the ends, remove yellow leaves. Make the sprouts look fresh and beautiful! Line the baking sheet with parchment paper to minimize the cleanup. Roast the Brussels sprouts with the cut sides down to provide for a beautiful roasted look.
- Use skinless, boneless chicken tenderloins. They are already usually precut and you can just add them to the skillet. If they are too thick, slice them into thinner strips.
- Fresh lemon. Use either 2 tablespoons of freshly squeezed lemon juice or just add 4 thin slices of lemon when you add garlic (and remove the lemon slices before serving).
What to serve with it?
This lemon garlic butter chicken is already a complete meal since it's made with roasted Brussels sprouts. If you would like to add carbs to it, serve this with rice, mashed potatoes, cauliflower rice, or lemon-flavored pasta.
How to store it
- Fridge. Lemon garlic butter chicken can be refrigerated in an airtight container for up to 4 days.
- Freezer. Freeze it in an airtight container for up to 2 months.

- 1 lb chicken tenderloins skinless, boneless
- ½ teaspoon smoked paprika
- ¼ teaspoon salt or to taste
- black pepper freshly ground, to taste

Instructions
How to roast Brussels Sprouts
- Preheat oven to 400 F. Line the baking sheet with parchment paper. Trim ends of Brussels sprouts and remove yellow leaves. Then, slice all Brussels sprouts in half.
- In a medium bowl, combine halved Brussels sprouts, 2 tablespoons of olive oil, salt and pepper to taste, and toss to combine. Spread Brussels sprouts on the baking sheet, cut sides down, without crowding.
- Roast in the preheated oven at 400 F for about 20 minutes.
How to make Lemon Garlic Butter Chicken
- If chicken tenderloins are too thick, slice them into strips. Season the chicken with smoked paprika, salt, and freshly ground black pepper.
- Heat 2 tablespoons of olive oil on medium heat in a large cast-iron skillet. Add the chicken in one layer and cook for about 3 minutes. Flip the chicken strips over and cook for 2 more minutes.
- Lower the heat to low, sprinkle the chicken with Italian seasoning and crushed red chili pepper flakes, add minced garlic, freshly squeezed lemon juice, and 3 tablespoons of butter. Cook for another 2 minutes or more, frequently stirring, until the chicken is cooked through but not overcooked.
- Add roasted Brussels sprouts to the same skillet with cooked chicken. Add 1 remaining tablespoon of butter and melt it on low heat, stirring it together with the Brussels sprouts. Do it rather quickly, for a couple of minutes, just until the butter melts and the lemon garlic butter sauce coats both the chicken and the Brussels sprouts evenly. Remove from heat.
- Stir in half of the chopped fresh parsley. When serving, top with the remaining half of chopped fresh parsley. Season with more crushed red chili pepper flakes, if desired.

It was quick to make and flavorful. I will make this recipe again.
This was a hit in my house! Very easy and flavorful. I made with a mix of sliced chicken breasts & thighs, because that's what we had on hand, and it came out great.
Very tasty and easy to make. It was our lunch for 2 today and my husband, a French chef, loved it. I made it without modifications or substitutions.
Could I use frozen brussel sprouts instead of fresh?
Very light dish. I served mine with white rice very delicious.
I just finished making this, I omitted the Italian seasoning, and forgot the parsley, but other wise it was pretty tasty. I served it with white rice. Very light dish.
I don't usually comment on recipes but this was DELICIOUS. I added half a package of bacon to make it a little more decadent (and served it with a baguette) but the basic sauce and flavors are AMAZING!
Still not sure how to make lemon garlic butter sauce.
Hi Heather, the instructions are in the recipe card, here is the shortcut to it: https://juliasalbum.com/lemon-garlic-butter-chicken/#recipe
This recipe was easy and sooo good! I did make a few adjustments since I did not have all of the ingredients. I substituted lime juice for lemon and no parsley. It still came out phenominal!!!
