Are tomatoes allowed in keto?

Yes. While tomatoes are technically a fruit, they're low in net carbs (~3.3g per medium tomato), making them keto-friendly in moderation.

How many carbs does a tomato pie have?

A traditional tomato pie can contain up to 40g net carbs per slice , but a keto version has just 4–6g net carbs , depending on ingredients.

Absolutely! As long as you use low-carb crusts and fillings, you can enjoy savory or sweet pies while staying in ketosis.

Store-bought sauces often contain added sugars. Always choose sugar-free versions or make your own to keep it keto.

Scale

Preheat oven to 375°F (190°C).
Mix all crust ingredients until combined, then press into a pie dish to form a crust.
Bake crust for 10-12 minutes until lightly golden. Let cool.
Layer sliced tomatoes and onions over the crust.
In a bowl, mix mayonnaise, cheddar cheese, oregano, and basil.
Spread the mayo mixture evenly over the tomatoes and onions.
Bake for 30 minutes until bubbly and golden on top.
Let cool slightly before serving.

Use firm, ripe tomatoes and pat them dry to avoid excess moisture. Oat fiber adds structure without carbs.
