Ingredients You’ll Need for Your Easy Keto Mustard Chicken
Gather your simple ingredients – you likely have most of these in your pantry already! This short list makes whipping up your Easy Keto Mustard Chicken a breeze.
- 🍗 2.5 pounds boneless, skinless chicken thighs
- 🧂 1/2 teaspoon salt
- 🍯 1/2 cup Dijon mustard
- 🍬 2 tablespoons keto-friendly sweetener (like erythritol or monk fruit blend)
- 🍎 1 tablespoon apple cider vinegar
- 🍁 1 teaspoon maple extract (optional, for a hint of sweetness)
- 🌿 1 tablespoon fresh rosemary, chopped
Detailed Step-by-Step Directions: How to Make Easy Keto Mustard Chicken
Ready to turn those simple ingredients into a masterpiece? Follow these easy steps to create your mouth-watering Easy Keto Mustard Chicken:
- Oven & Dish Prep: Start by preheating your oven to a cozy 350°F (175°C). Grab a casserole dish and give it a quick spray with cooking spray – this helps with easy cleanup later!
- Chicken Arrangement: Carefully place your boneless, skinless chicken thighs in a single, even layer in your prepared casserole dish. A uniform layer helps them cook evenly. Sprinkle them generously with the salt.
- Whip Up the Magical Sauce: In a separate mixing bowl, combine your Dijon mustard, keto-friendly sweetener, apple cider vinegar, the optional maple extract, and your fragrant fresh rosemary. Whisk everything together until you have a smooth, harmonious sauce.
- Coat and Initial Bake: Now for the fun part! Pour that incredible mustard sauce all over the chicken thighs, ensuring every piece is beautifully coated. Pop the dish into your preheated oven and bake for 40 minutes.
- Baste and Finish: After 40 minutes, gently pull the dish out of the oven. Spoon some of that delicious sauce from the bottom of the dish over the chicken – this is called basting, and it locks in moisture and boosts flavor! Return the dish to the oven for an additional 20 minutes of baking.
- Serve and Savor: Once the total hour is up, your chicken should be wonderfully tender, and the sauce perfectly thickened. Dark meat chicken is incredibly forgiving, so don’t worry about it drying out – it just gets more succulent! Let it rest for a few minutes before serving.
Presenting and Serving Your Easy Keto Mustard Chicken
This Easy Keto Mustard Chicken is a star on its own, but it truly shines when paired with the right sides. Here are some fantastic keto-friendly ideas to complete your meal and impress your family or guests:

- Zoodle Delight: For a lighter option, serve over a bed of sautéed zucchini noodles (zoodles) or spiralized cucumber. The sauce clings beautifully to them!

Storing Your Easy Keto Mustard Chicken: Freshness & Longevity
Got leftovers of your delicious Easy Keto Mustard Chicken? Fantastic! This recipe is excellent for meal prep and stores beautifully, ensuring you can enjoy its flavors for days.
- Refrigeration: Once cooled to room temperature, transfer any leftover chicken and sauce to an airtight container. It will keep fresh in the refrigerator for 3-4 days.
- Freezing: For longer storage, this dish freezes surprisingly well! Place the cooled chicken and sauce in a freezer-safe bag or container. It can be frozen for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: To reheat, simply warm the chicken in the microwave until heated through, or gently in a pan on the stovetop over medium-low heat, adding a splash of chicken broth or water if the sauce seems too thick. You can also reheat it in the oven at 300°F (150°C) until warmed.
FAQs About Easy Keto Mustard Chicken

A1: Yes! With 1g total carbs and 0g net carbs per serving, it’s perfectly suited for a ketogenic diet.

Q6: Can I use dried rosemary instead of fresh?

Q7: How do I know when the chicken is cooked through?

Q8: Can I make this in an Instant Pot?
A8: While possible, this recipe is designed for baking, which allows the sauce to thicken beautifully. Pressure cooking yields a different texture.
Q9: What other sweeteners can I use?
A9: Any granulated keto-friendly sweetener like allulose, stevia blend, or xylitol (not for pets) works well.
