Why do I love Lakanto Golden Monkfruit Sweetener?
- TASTES LIKE SUGAR: Contains zero net carbs, zero calories, and is zero-glycemic. Perfect for cookies, coffee, desserts, and other sweet, sugar-free treats.
- 1:1 SUGAR REPLACEMENT: Lakanto Monkfruit Sweetener matches the sweetness of sugar, helping you fill your kitchen with a healthy cup-for-cup alternative to ordinary baking and cooking ingredients.
- LIFESTYLE FRIENDLY: Works with ketogenic, diabetic, candida, paleo, vegan, low-carb, low-sugar, non-GMO, and all-natural diets.
- CLASSIC, GOLDEN & POWDERED: Golden Lakanto is a raw cane sugar substitute, Classic White is a white sugar substitute, and Classic Powder is a powdered sugar substitute.
- INGREDIENTS: The perfect mix of monk fruit extract and erythritol with no fibre, no maltodextrin, and no artificial flavouring or sweeteners.
What if you can't find Lakanto Golden Monkfruit?
You can make your own "brown sugar" sweetener using any type of erythritol or granular type sugar replacement by simply stirring 1 cup of sweetener with 1 tablespoon of molasses or sugar-free maple syrup.
How do you prepare this low-carb and healthy Grilled Keto Sweet Mustard Chicken?
- Combine the mustard, sweetener and spices in a small bowl and stir to incorporate
- Remove ¼ cup of the mixture and set it aside
- Add chicken to the bowl and toss to coat.
- Let the chicken sit for 20-30 minutes.
How do you cook this keto chicken dinner?
If cooking the chicken on the grill:
- Heat grill on medium heat and add chicken.
- Grill 6-7 minutes on each side or until the chicken reaches 165 degrees F.
- Serve with the reserved mustard glaze
*Mr. Grumbles did our grilling and he suggests 3 minutes a side and then repeat for an additional 2 minutes per side to get a slight char on the chicken*
If baking the chicken in the Oven:
- Preheat the oven to 425 degrees F
- Line a baking sheet with parchment paper
- Add chicken to a baking sheet and bake for 20 minutes, flipping chicken after 12 minutes or until the internal chicken temperature is 165 degrees F.
- Serve with the reserved mustard glaze
Can I use chicken breasts instead of chicken thighs?
You can use chicken breast meat instead of thigh meat.
I prefer chicken thigh meat when I am baking or grilling chicken as it has a tendency to retain more moisture and doesn't dry out as easily as chicken breast meat.
If you want some chicken breast recipes, check out my Whole30 Creamy Ranch Chicken, Buffalo Chicken Dip or Chicken Artichoke Dip recipes.
Can I use chicken thighs that still have the bone and skin on them?
Absolutely!
Bone-in chicken thighs will take longer to bake than boneless so keep that in mind.
In the oven, they will take between 35-45 minutes as for the grill, add an additional 6-10 minutes depending on the size and thickness of the thighs.
What can I substitute if I don't have some of the ingredients listed?
Lakanto Golden Monkfruit:
- replace with equal amounts of brown sugar
- replace with equal amounts of erythritol mixed and add 1-2 teaspoon of sugar-free maple syrup or molasses
Dijon Mustard:
- replace with regular yellow mustard
Nutritional Yeast:
- replace with 1-2 tablespoon Parmesan cheese
Allspice:
- add a pinch of nutmeg, cinnamon and clove
