Heat a tablespoon of olive oil in a medium saucepan over a low heat. Crush the garlic and add to the saucepan. Sweat gently for 2-3 minutes until tender and fragrant.
Step 2
Add the tomato sauce to the saucepan. Add the thawed spinach and basil. Stir well to combine, heating through for a minute.
Step 3
Add the zucchini noodles to the saucepan. Stir well to combine and heat through for just a few minutes until everything is hot through and the zucchini is tender. Do not overcook, as the zucchini will become overly soft and release too much liquid.
Step 4
Divide the spaghetti evenly between two serving bowls. Drizzle with the remaining olive oil and scatter over the parmesan shavings to serve. Serve hot with your preferred Keto sides.
