Thanksgiving is just days away and I couldn’t wait to share my absolute favorite keto portobello mushroom recipe with you.

I know we’re all in the search for the perfect side to our juicy and flavorful turkey. That’s why I am introducing you to this absolutely delightful dish.

Ever since I was little, I’ve always loved mushroom dishes. For years, I’ve tried to create the ultimate keto side dishes for dinner.

I wanted to create a side dish with the most flavorful stuffing, and now, I’ve finally done it just in time for my thanksgiving dinner.

Of course, I’m sharing this with you guys since I figured you’re going to be able to reunite with your family for the holidays this year, and if you’re trying to keep keto you’ll probably need to bring your own side dishes to dinner like I will.

This year’s Thanksgiving is going to be one for the books! I mean everyone in one place enjoying a meal? Epic!

I won’t have to endure a ZOOM Thanksgiving now, like we did last year. I can finally share this amazing keto portobello mushroom recipe with my family and friends.

Keto Portobello Mushroom Recipe Ingredients: 

  • 9 sweet Italian sausages, without casing

  • 2 tbsp olive oil

  • 6 large portobello mushrooms

  • 3 cloves minced garlic

  • 9 large fresh sage leaves, chopped fine (or 1 tbsp of dried sage)

  • 1/2 tsp fresh thyme leaves (or ¼ tsp dried thyme)

  • 1/2 tsp salt

  • 6 oz cream cheese

  • 1/3 cup almond flour

  • 3 tbsp fresh chopped parsley

  • 1 cup mozzarella cheese

Keto Thanksgiving Sides

As we know, to have a great meal we not only have to concentrate on the main dish but we also have to make sure that everything, including the sides, are perfect.

This is just one of the many reasons why I made low carb Italian sausage recipes. I also love sausage and mushrooms too much not to include in my meal.

Fortunately, we now have this wonderful keto portobello mushroom recipe to bring to the table. It’s easy to make, so you won’t need to spend so much time with it, and it is keto friendly.

Even with the holidays, you don’t need to worry about falling off the wagon or getting kicked out of your ketogenic diet.

With my keto side dishes for dinner, Thanksgiving is going to be as good as always.

At least now, I can bring something to the table that I actually created and cooked myself- I didn’t just help my parents prepare it in the kitchen. It just feels good to cook for the family and have them enjoy new flavors.

And this dish is so tasty that your family is not going to know the difference between the keto and the regular version of it.

Is Italian Sausage Keto?

Yes, actually. Italian sausage is keto-friendly. If you want to get technical, a 100-gram serving of pork sausage contains approximately 18 grams of fat, 27 grams of protein, and 0 grams of carbs.

This makes it keto friendly, as well as relatively easy to fit into some low carb Italian sausage recipes.

Generally, sausage is assumed to be keto-friendly because most of its contents include beef, pork, poultry, chicken, or turkey, as well as a handful of other ingredients to add flavor and texture.

As we know, these types of meat are quite high in protein, but relatively low in carbs. To give you an idea, here is a list of sausages and their carb content per 100 g serving:

  • Andouille sausage: 3 grams
  • Beef sausage: 0 grams
  • Bratwurst: 3 grams
  • Breakfast sausage links (pork or turkey): 1 gram
  • Chicken sausage: 4 grams
  • Chorizo: 2 grams
  • Italian sausage: 4 grams
  • Pork sausage: 0 grams
  • Salami: 6 grams
  • Turkey sausage: 3 grams
  • Vienna sausage: 2 grams

One of the best types of sausage to shop for on a keto diet include summer sausage, chorizo, Vienna sausage, chicken spinach sausage links, pork bratwurst, and Italian sausage sliders.

If you’re shopping for sausages to incorporate in your low carb Italian sausage recipes, you should definitely look at the ingredients when looking at the nutritional label.

In addition, try to also check the net carb count, sugar count, and whether or not it’s gluten-free.

The net carb count is the number of carbs absorbed in your body. If you want to calculate the net carbs, subtract the fiber from the total number of carbs.

Since the standard ketogenic diet requires that you stay between 20-50 grams of net carbs per day to maintain ketosis, if your sausage fits within that net carb count, you are all set to enjoy some sausage.

Also, ensure that the sugar count is low. After all, any sugar listed on the ingredients label is most likely artificial. Avoid the additives and extra carbs by buying a sausage with no added sugar or corn syrup.

Portobello Mushroom Carbs

As we have established before, in keto, your diet is designed to be very low in carbohydrates and high in fat with moderate amounts of protein.

As such, we need to also make sure whether or not portobello mushroom can be counted as keto friendly.

According to healthline, the most common types of mushrooms are naturally low in carbohydrates in their natural form.

In fact, a cup (or a 96-gram) serving of raw, whole white button mushrooms contains 3 grams of carbs.

Portobello mushrooms, our main character, also has around 3 grams of carbs in both a 1-cup (86-gram) serving of them diced, or an average mushroom cap you might use to make a meatless burger.

However, we should also know that mushrooms are not only low in carbs, but also high in fiber.

Fiber can be tough to get on the keto diet since it’s found in carb-rich foods like fruits, vegetables, and whole grains. This is why we have to look for low carb foods that pack fiber, such as mushrooms, avocado, nuts, and seeds.

While it’s definitely a possibility, it’s also highly unlikely that you would go over your daily carb limit by making mushrooms a regular part of your diet, unless you’re planning to eat 6 cups a day or preparing them as part of an otherwise carb-heavy grain dish.

If you’re shopping for canned or packaged mushroom products, be sure to read the nutrition label, as these may not be as keto-friendly.

Keto Side Dishes For Dinner

This year’s Thanksgiving dinner will be extra special. Since last year was especially hard to have family dinners without running the risk of getting sick, this year will be extra special.

Now we get to share a meal with our families and friends and this side dish is guaranteed to be a hit just like the classic turkey stuffing.

Contrary to popular belief, keto thanksgiving it’s never boring or lacking in flavor. I’ve made sure to share dishes with you that will put an end to the thought of having to cheat during certain food centered holidays.

With so many of my keto sides and main dishes to choose from, you’ll have variety and feel totally satisfied during your keto holiday.
