Table of Contents

Introduction

This recipe is a delicious way to include spaghetti squash in your diet. It’s Asian-inspired with crispy baked tofu, roasted vegetables and an easy coconut peanut sauce to top it all off.

Using spaghetti squash in place of rice or noodles is a great way to get more fiber into your diet and makes a good option for those eating a lower carbohydrate diet.

Ingredient Notes

Spaghetti Squash: Don’t worry about the exact size of squash used. Roughly 1 medium to large squash or 2 small ones is about right.
Tofu: Extra firm tofu is recommended but firm would also be ok.
Cornstarch: You can substituted arrowroot powder.
Vegetables: The recipe calls for broccoli, bell pepper, red onion and carrot but you mix and match with other veggies like cauliflower, zucchini, mushrooms or anything else you enjoy.
Almond Butter: The sauce can be made with peanut butter or almond butter.
Coconut Milk: Canned light coconut milk is best here, I don’t recommend using full-fat or it will be too thick. If you’d prefer a peanut sauce without coconut milk, you can use the ginger peanut sauce from this Peanut Tofu Bowl recipe or the spicy peanut sauce from this Cold Asian Noodle Salad.

This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.

Additions and Variations

You could use chickpeas as an alternative to tofu or they can be added to the recipe. Toss them with 1 tsp oil, salt and pepper and add to the pan with the squash.
Tempeh can also be used instead of tofu. You can use it in place of the tofu directly or make the marinated tempeh from this High-Protein Vegan Salad recipe.
If you want to add an Asian green like bok choy, I’d suggest steaming it separately.
