Core Ingredients Guide

Tomatoes The Star

Choose a highquality canned whole peeled tomato, preferably SanMarzano or nopeel varieties. Theyre low in natural sugars (<2g per cup) and give a richer texture after roasting.

Aromatics & Herbs

Fresh garlic (2cloves), a splash of onion powder (optional), dried oregano, basil, and a pinch of redpepper flakes for a gentle kick.

Seasonings

Sea salt, freshly cracked black pepper, and a drizzle of olive oil if youre not going oilfree. For a keto version, add a tablespoon of extravirgin olive oil to boost healthy fats.

Ingredient Checklist

2cans (28oz each) nopeel whole tomatoes, drained
2garlic cloves, minced
1tsp dried oregano
1tsp dried basil
tsp redpepper flakes (optional)
tsp sea salt
tsp black pepper
1tbsp olive oil (omit for oilfree)

StepbyStep Recipe

1. Roast the Tomatoes

Preheat your oven to 425F (220C). Toss the drained tomatoes with a little olive oil (or a quick spray of water if youre avoiding oil), salt, and pepper. Spread them on a baking sheet and roast 2025minutes until the edges caramelize. This step deepens the flavor and naturally sweetens the sauce without any sugar.

2. Blend the Base

While the tomatoes roast, mince the garlic and gather your herbs. Once the tomatoes are nicely browned, transfer them to a blender with the garlic, oregano, basil, and redpepper flakes. Blend on high for about 30 seconds until smooth. If you prefer a chunkier texture, pulse instead.

3. Adjust the Taste

Give the sauce a quick taste. If it feels a tad acidic, add a splash (tsp) of balsamic vinegar or a pinch of smoked paprika. Both give a subtle sweetness without adding sugar.

4. Cool & Store

Let the sauce cool to room temperature, then pour it into airtight jars. It lasts up to 7days in the fridge or 3months in the freezer. For freezerfriendly portions, use an icecube tray, then transfer the frozen cubes to a ziplock bag.

Pro Tips

For a richer keto sauce, stir in an extra tablespoon of olive oil after blending.
If youre avoiding oil completely, substitute with a splash of lowsodium vegetable broth while roasting.
