The Secret to the Perfect Garlic Herb Marinara Sauce
What truly sets this dish apart is the garlic herb marinara sauce. Packed with fresh herbs, savory anchovies, and aromatic garlic, this sauce transforms the humble spaghetti squash into something extraordinary.

Anchovy Fillets – A Game-Changer for Flavor
If you’ve never used anchovies in your marinara sauce, you’re missing out. The anchovy fillets dissolve into the olive oil, creating a deep umami flavor that infuses the sauce with richness. Don’t worry; you won’t taste the anchovies directly—they dissolve and contribute to the savory backbone of the sauce, enhancing the overall depth of flavor. It’s a secret ingredient that makes the marinara taste even more irresistible.
Fresh Herbs for a Burst of Flavor
The combination of oregano, parsley, and basil makes this marinara sauce truly shine. Fresh herbs bring out the bright, vibrant flavors that make this sauce so delightful. Oregano adds a slightly earthy taste, while basil contributes a touch of sweetness, and parsley gives it a fresh finish. Together, these herbs transform a simple marinara into a robust, flavorful sauce.
The Role of Sugar in Balancing Acidity
Tomatoes can sometimes be overly acidic, which is why adding sugar to the marinara sauce helps balance out the flavors. The sugar mellows out the sharpness of the tomatoes, creating a smoother, well-rounded sauce that’s not too tangy but just right.
How to Cook Spaghetti Squash – Step-by-Step
Roasting spaghetti squash is easy, and with the right technique, you’ll achieve perfectly tender strands every time. Here’s how you do it:
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). The high heat will allow the squash to roast evenly, caramelizing the edges while softening the flesh.
Step 2: Cut and Prepare the Squash
To prepare the squash, slice it in half lengthwise. Be sure to use a sharp knife to make a clean cut. Once it’s halved, scoop out the seeds and membranes with a spoon. This will give you a clean cavity to roast.
Step 3: Season the Squash
Brush the cut sides of the squash with 1 tablespoon of olive oil. This helps the squash roast evenly and prevents it from sticking to the pan. Season with salt and pepper to taste. Don’t be shy with the seasoning—this is the base of your dish, and you want it to be flavorful.
Step 4: Roast to Perfection
Place the squash halves, cut-side up, on a large baking sheet. Roast for 45 to 60 minutes, depending on the size of the squash. A smaller squash may cook faster, around 25 to 30 minutes. Check for doneness by gently prying at the flesh with a fork; if it separates easily into strands, it’s done.
Step 5: Scrape and Drain
Once the squash is roasted, remove it from the oven and let it cool for a few minutes. Using a fork, gently scrape the flesh into strands. Be sure to allow any excess liquid to drain off, so you end up with light, fluffy strands rather than a soggy mess.
Cooking the Shrimp – Simple and Quick
Shrimp cooks quickly, making it the perfect protein to pair with your roasted spaghetti squash and marinara sauce. Here’s how to make sure the shrimp turns out perfectly:
Step 1: Peel and Devein the Shrimp
Start by peeling the shrimp and removing the vein. This step is essential for both presentation and texture. You can buy pre-peeled and deveined shrimp to save time, but doing it yourself ensures the freshest shrimp possible.
Step 2: Sauté the Shrimp
In a large skillet, heat 3 tablespoons of olive oil over medium-high heat. Once the oil is hot, add the shrimp and sauté for about 1 to 2 minutes on each side, until they turn pink and curl slightly. Shrimp cooks very quickly, so keep an eye on them to avoid overcooking.
Step 3: Add to the Sauce
Once the shrimp are perfectly cooked, spoon some of the garlic herb marinara sauce over them, allowing the flavors to meld together. Let the shrimp cook in the sauce for an additional 3 to 4 minutes, ensuring they are evenly coated and infused with the marinara’s rich flavors.
Assembling the Dish – Bringing it All Together
Now that your squash is roasted, your marinara sauce is simmering, and your shrimp are perfectly cooked, it’s time to assemble the dish.
Step 1: Plate the Spaghetti Squash
Start by placing a generous portion of spaghetti squash strands on each plate. You want a nice pile, as the squash serves as the base of the dish.
Step 2: Top with Marinara and Shrimp
Next, spoon the garlic herb marinara sauce with shrimp over the squash. Be generous with the sauce, making sure to coat every strand of squash with the flavorful, herb-infused tomato sauce.
Step 3: Garnish with Parmesan
Finish the dish by garnishing it with freshly grated Parmesan cheese. This adds a touch of richness and a savory contrast to the sweetness of the marinara and the delicate flavor of the shrimp.

Ingredients
- 2 large spaghetti squash
- 4 tablespoons olive oil (divided)
- 1 can anchovy fillets
- 4–5 garlic cloves, minced
- 1 sweet onion, thinly sliced
- 1 serrano chile, minced (optional)
- 28 oz can whole tomatoes
- 7–8 fresh oregano leaves
- 1/4 cup fresh parsley, coarsely chopped
- 1/2 cup fresh basil leaves, torn
- 2 tablespoons sugar
- 1 lb large shrimp, peeled and deveined
- Parmesan cheese (for garnish)
Instructions
- Preheat your oven to 400°F. Cut the spaghetti squash in half, remove the seeds and membranes, and brush the cut sides with 1 tablespoon of olive oil. Place the squash cut-side up on a large baking sheet and season with salt and pepper. Roast in the oven for 45-60 minutes, or until the squash is fork-tender (smaller squash may cook faster, in 25-30 minutes).
- While the squash is roasting, heat 3 tablespoons of olive oil in a large skillet over medium-high heat. Add the anchovy fillets, letting them dissolve into the oil. Add the garlic, onion, and serrano chile, if using. Lower the heat to medium and sauté until the onions are soft and translucent.
- Cut the tomatoes in half and add them to the skillet with their juices, stirring to combine. Add the oregano and simmer the mixture for 15 minutes, allowing the liquid to reduce. Stir in the parsley, basil, and sugar, then continue cooking over low heat.
- Add the shrimp to the skillet, spooning the sauce over them to ensure they cook evenly. Cook for 5-6 minutes or until the shrimp turn pink and curl slightly.
- Check the spaghetti squash; when it’s done, the skin should be crispy and the flesh should separate easily into strands when scraped with a fork. Remove from the oven, place the squash halves on a cooling rack over a baking sheet, and rake out the flesh with a fork, allowing any excess liquid to drain off.
- Serve by placing a pile of spaghetti squash on each plate, topping with the roasted marinara and shrimp, and garnishing with freshly grated Parmesan cheese if desired.
