Ingredients for this recipe

You’ve probably already got the ingredients you’ll need on hand to make this.  Here’s what to gather up from your kitchen:

  • Olive oil
  • Lemon
  • Dried rosemary
  • Dried thyme
  • Salt and pepper
  • Optional but not shown: garlic

That’s it!  You’ll whisk together your ingredients then pour them over your chicken in a zip loc bag or bowl.  We usually use this marinade with about 1 ½ pounds of raw chicken breast.

Macronutrient breakdown:

Marinades are interesting to try to calculate nutrition facts on.  While it’s easy to simply add up all the ingredients, it ignores the fact that you don’t actually eat the entire amount.  In fact, a chef friend of ours said that most animal proteins usually retain about 10% of the total marinade. 

We’ve calculated it at 20% to leave a little margin of error, just in case, and we’re assuming you’re using 1 ½ pounds of chicken breast to give you four servings of chicken.  Raw chicken to cooked chicken is about a 25% weight change, so each serving of cooked chicken would be about 4.5 ounces.

Phew – now that all those assumptions are made, we can figure out that each serving of chicken with marinade contains 225 calories and less than half a gram of net carbs.  The specific breakdown is:

  • 30% fat
  • <1% carbs
  • 68% protein

Now you might be a little nervous, because that seems like a lot of protein in comparison to fat.  Naturally, a leaner piece of meat like chicken is going to be more protein heavy.  BUT this is where you can add in a nice fatty side dish to have a more well-balanced meal that gets your fat macros up a bit!

High fat side dishes to go with this meal:

To achieve your best keto macros for this meal, add in a high fat side dish (or structure your other meals in the day to be concentrated in fat).  Here are some ideas that combine nutrient-rich veggies with high fat accompaniments:

  • Steamed or roasted broccoli topped with lots of our keto queso
  • Cheesy zucchini gratin
  • Bacon-wrapped green beans (Just wrap bunches of 4-5 (raw) green beans with a piece of bacon, and bake in the oven at 375 for 30-40 minutes until the green beans are tender and the bacon is cooked through.  I know people like to blanch the green beans ahead of time but I swear by this easier method, as the green beans cook in the bacon fat!)
  • Smashed cauliflower made with cream, cheddar cheese, bacon, and chives
  • Keto creamed spinach

How to make other delicious marinades

While I’ve got the great Italian combination for you here, I thought it might be helpful to share some info about just creating your own marinades in general.  That way, if you want to whip up different combinations on your own, you know how!

My wife taught me that the key to any good marinade is generally a combination of four elements:

1) Fat:  We veer towards extra virgin olive oil for much of our cooking, but avocado oil is also an excellent choice here.

2) Acid:  Lemon juice, lime juice, or any type of vinegar can be used to add the acidic component, which is thought to help tenderize the meat and add a balance of flavor.  Sometimes, acidic dairy products like sour cream or buttermilk are used.

3) Flavor:  Get creative here!  Herbs and spices are clearly a go-to option, from the Italian seasonings like rosemary and thyme used in this recipe – or Mexican-inspired seasonings like cumin and chili powder that can be used in other marinades.  But you can also think of other flavor elements here too – for example, ginger, citrus zest, soy sauce, fresh chilis, or garlic.  Keto-friendly sweeteners like allulose, monkfruit, or erythritol might be also used depending on the type of marinade (for example, a teriyaki style sauce would often include a sweetener).

4) Salt:  Technically, this is optional – but definitely recommended.  You don’t want to go overboard, and the purpose is not to make it taste salty.  However, salt (or sodium found in sauces like soy sauce) help to bring out the rest of the flavors in a dish.

Of course, there are some exceptions to this rule, so don’t take this as the be-all, end-all of marinating.  But the possibilities are really endless if you loosely follow a breakdown like this.  For example:

  • Teriyaki style: sesame oil, soy sauce, rice vinegar, Lakanto golden, ginger, garlic, green onions
  • Keto honey mustard marinade (I use this to coat my keto pork chops – kind of more along the lines of a sauce in that recipe but you can use as a marinade too): Mayo, mustard, Lakanto golden, garlic powder, paprika, salt, pepper
  • Mexican style marinade: olive oil, lime juice, garlic, cumin, chili powder, salt, pepper
  • Balsamic marinade: olive oil, balsamic vinegar, optional Lakanto golden, garlic, salt, pepper
  • BBQ style: Use our keto BBQ sauce recipe to marinate!

Store bought low carb marinades

If you don’t feel like whipping up your own, you may find that several keto-friendly marinades on the market that can be used on chicken, beef, fish, or other proteins.  Don’t forget to look at regular sauces and dressings that aren’t necessarily labeled as marinades, as most are versatile!  Below are a few of my favorites:

*Quick note – I personally believe that a keto diet is based on the metabolic state of being in ketosis – not an arbitrary “off-limit” list of ingredients that the diet market has capitalized on.  While most products that contain sugar are off the market, sometimes marinades will contain very small amounts of sugar.  As long as you are using it in the correct serving size – i.e. the amounts here that contain 1-2 grams of net carbs per serving – it should by no means kick you out of ketosis despite seeing it in the ingredients.  If you disagree with this definition, feel free to skip over these recommendations and choose your own.*
