Vegetarian Spaghetti Sauce Recipe

Since the new year started, I thought it would be fun to intensify my workouts and actually try to build some muscle. This is actually only halfway true—yes, I’ve intensified my workouts and, yes, I am working to build more muscle, but the real reason for all of this is that I hurt my achilles tendon and can’t run like I used to. This means more strength training, more high-intensity workouts that don’t involve running, and swimming.

Long story short—I want to eat everything. All the time. But mostly, I really want protein.

So, that’s what I’ve been doing—eating protein—and it’s been fun, but I knew there had to be a yummy protein-packed, plant-based meat alternative to replace ground beef and help me (and my family) eat a little better. That’s when I found HAPPY LITTLE PLANTS® Product at my local Safeway store (right where you’d find regular ground beef).

HAPPY LITTLE PLANTS® Plant-Based Ground

Before I dive into this vegetarian spaghetti sauce recipe and how to make it, let’s chat a minute about this plant-based meat alternative and why I actually like it.

  • First, and most important, it cooks just like regular ground beef or turkey. HAPPY LITTLE PLANTS® product requires no special cooking equipment or techniques outside of that which you already use to cook meat.
  • It’s better for the planet.
  • It’s a blank canvas, allowing you to add all your favorite flavors and seasonings.
  • HAPPY LITTLE PLANTS® product has far fewer calories and saturated fat compared to other plant-based meat brands*.
  • There are ZERO preservatives.
  • And it is completely gluten-free.

How to Cook Vegetarian Spaghetti Sauce

For the full list and amounts of ingredients, scroll down to the recipe card at the bottom of the page.

Step 1: How to cook HAPPY LITTLE PLANTS® product:

  1. Place 2 tablespoons of oil in a large nonstick skillet.
  2. Heat oil over medium heat for 2 minutes.
  3. Add the ground meat alternative to your skillet and break apart into pieces. Gently stir to lightly coat with the oil.
  4. Cook, stirring occasionally, until the product reaches an internal temperature of 165°F, as measured by a meat thermometer—about 10-12 minutes.
  5. Season as desired. For this recipe, I added salt, Italian seasoning, dried basil, onion powder, garlic powder, and black pepper to the ground meat alternative towards the end of cooking. Mix well to combine and cook for an additional 1 minute before removing from heat. Set aside.

Step 2. Make your Vegetarian Spaghetti Sauce

  1. Add the remaining tablespoon of oil to a large saucepot over medium-high heat. Add the diced onion, and cook for 5-7 minutes or until soft and translucent—stirring often. Once softened, add the minced garlic and tomato paste. Mix well to thoroughly combine. Cook, stirring continuously, for 1 minute.
  2. Stir in the crushed tomatoes, tomato sauce, and water. Add the cooked ground meat alternative back to the pot. Mix well to combine, and bring to a low simmer. Reduce heat to medium-low, cover, and allow the sauce to simmer for at least 20 minutes.
  3. Season with additional salt, pepper, and Italian seasoning as desired.

How to Serve Vegetarian Spaghetti Sauce

So, you’ve made a big pot of simmering, delicious plant-based spaghetti sauce – now what? You enjoy it, of course! Just as you would another other meat-filled spaghetti sauce! Except for this time, there’s no meat! Here are some ideas to get you started.

  1. Pizza. Add this as the protein-packed plant-based sauce to all your favorite homemade pizza recipes.
  2. Stuffed bell peppers. This is one of my favorites. I can almost guarantee that your family won’t even notice the lack of ground beef or ground turkey.
  3. Make some cheesy stuffed shells and top with leftover spaghetti sauce.
  4. Meal-prep or enjoy the next night for spaghetti dinner round two!
  5. LASAGNA!
  6. Twice-baked spaghetti squash (full instructions below).

Twice-Baked Spaghetti Squash with Vegetarian Spaghetti Sauce

Trust me, you’ll love this! It’s a bit more work, but they reheat really well and require only two additional ingredients:

  • Spaghetti squash
  • Shredded mozzarella cheese.

How to cook spaghetti squash:

  1. Preheat oven to 400 degrees F, and line a large baking sheet with parchment paper.
  2. Scrub the squash clean, and dry thoroughly. Cut the squash in half lengthwise using a sharp knife. Scoop out the seeds and stringy bits and discard.
  3. Drizzle the squash with olive oil, and use a pastry brush (or your hands) to brush over the entire surface of the squash. Sprinkle with salt and pepper, and place cut-side down on the lined baking sheet.
  4. Place squash in the oven, and bake for 45 minutes to 1 hour or until squash is tender when pierced with a fork.
  5. When cool enough to handle, gently scrape out the squash with a fork to remove the flesh in long strands (see image below).

Twice-bake your spaghetti squash:

In this step, add as much or as little spaghetti sauce as you’d like.

  1. Preheat oven to 350 degrees F.
  2. Gently scrape the spaghetti squash strands from each squash half (if you haven’t already).
  3. Add approximately 1 – 2 cups of prepared vegetarian spaghetti sauce to each squash boat, and gently mix with the separated strands of squash. Repeat with all squash boats.
  4. Divide the shredded mozzarella cheese between the squash boats. Cover the baking sheet and squash with foil, creating a tent to prevent the foil from touching the cheese.
  5. Bake at 350 degrees for 15 minutes. Remove the foil tent, and bake an additional 5-10 minutes or until cheese is golden and bubbly.

Can you Freeze Leftover Vegetarian Spaghetti Sauce?

Yes.

First, allow your sauce to cool to room temperature before transferring to freezer bags or containers. You may choose to freeze your leftovers as individual servings (enough for one or two) or all together in one gallon-sized ziplock bag—this is up to you. Remove as much air as possible, and transfer to the refrigerator to cool overnight. The next morning, transfer to the freezer and store for up to three months.

To reheat, allow your sauce to thaw in the refrigerator overnight. The next day, transfer to a pot and gently heat over medium heat—adding more water or broth as needed. You may also heat in the microwave at high heat for 1 – 2 minutes.
