Polenta, a creamy, dreamy dish from northern Italy, is a delicious gluten-free ingredient, but if you’re following a ketogenic diet, you might wonder: is polenta keto? Spoiler alert—traditional polenta is not exactly a friend to low-carb living. But don’t worry, we’ll break it all down and even give you some keto-friendly alternatives (hello, cheesy keto polenta!).
About polenta
Polenta has been a staple for centuries. It’s warm and comforting and pairs beautifully with olive oil, parmesan cheese, and even a bit of turmeric sprinkled on top for added flavor.
Traditional polenta is made from coarsely ground cornmeal, and because cornmeal is naturally high in carbs, polenta isn’t a great fit for a keto diet.
A typical serving (about 100g) contains anywhere from 15g to 30g of total carbs, which can quickly take up a large portion of your daily carb allowance if you’re aiming to keep things low carb.
When you’re trying to maintain a strict keto diet with only 20-50 grams of net carbs per day (or lower), consuming a serving of polenta can eat up (no pun intended) a large chunk of that limit, leaving less room for other nutrient-dense, low-carb foods.
Since cornmeal is derived from corn—one of the highest-carb grains—it’s clear why polenta is considered a non-keto ingredient and generally off-limits for anyone sticking to a ketogenic plan or focusing on low-glycemic, grain-free living.
Pre-made polenta, or polenta that is pre-cooked and then packaged, ready for re-heating is even more of a no-go for strict keto followers due to supermarket food additives and non-keto ingredients.
Plus, it often contains common ingredients like artificial sweetener or preservatives that can mess with ketosis.
Even though pre-made polenta may look like a simple solution for a quick meal, these added ingredients can disrupt your body’s ability to stay in a fat-burning state.
Net Carbs in Polenta vs. Keto Macros
For those using a keto macros calculator, the net carbs in polenta can be a bit of a shock. For most people following a ketogenic diet, even a small bowl of polenta could take a great deal of your daily carb intake.
The Breakdown
- Total carbs in polenta: ~20g per 100g serving
- Dietary fiber: ~2g
- Net carb consumption: ~18g per 100g serving
That’s a pretty hefty hit to your daily value of carbs whether you’re aiming for ketosis or eating to maintain balanced blood sugar.
Keto-Friendly Alternatives to Polenta

By combining cauliflower rice with almond meal and extras like butter and Parmesan, you'll get a delicious low-carb polenta alternative!

Cheesy Low-carb Grits
My cheesy low-carb grits are similar to my low-carb polenta, but with a smoother consistency and extra butter and cheese.
One of the great things about this recipe is it's just as versatile as it is creamy and indulgent, so feel free to add in your favorite cheeses, herbs, and spices! Enjoy them with keto shrimp and grits for a delicious, Cajun-inspired meal.

A simple cauliflower mash is a great alternative to polenta, and is just as capable of being a neutral base.
I have recipes for a creamy dairy-free mashed cauliflower as well as a roasted mashed cauliflower with garlic. Both are keto-friendly, low-carb, and so good.
How to Fit Polenta into a Keto Diet
While polenta may not be a go-to option for those on a keto diet, it’s still possible to enjoy it in moderation. And with a few adjustments, of course!
Here’s how you can sneak polenta into your meals without throwing off your carb count:
- Keep portions small– Stick to very small servings (think ¼ to ½ cup) to keep carbs in check.
- Pair it right – Combine this higher-carb dish with healthy fats, protein, and fiber. This can help keep blood sugar stable and prevent a large spike.
- Adjust your other meals – Modify the rest of your daily diet to accommodate the extra carbs from the polenta without exceeding your daily limit.
The Verdict: Is Polenta Keto?
Sorry to say, but traditional polenta is not keto-friendly. However, with great examples of foods like cauliflower rice and almond flour, you can still enjoy the textures of a true soft polenta without breaking your keto diet plan.
Next time you’re craving polenta, try a keto-friendly version instead. Your macros will thank you!
