• 0.5 tbsp (7.4ml) avocado oil
• 6.0 oz (177.4ml) chicken broth

Step-by-Step Instructions

Following these steps ensures the sauce develops a deep, rich profile without overcooking the delicate seafood.

1. Combine the crushed tomatoes, chicken broth, avocado oil, minced garlic, salt, seasoned salt, black pepper, red pepper flakes, dried basil, and dried oregano in a 4-quart slow cooker.
2. Stir the mixture thoroughly to ensure the spices and oils are evenly distributed throughout the tomato base.
3. Secure the lid on the slow cooker and set the temperature to the low heat setting for a duration of 4.0 to 5.0 hours.
4. Open the lid once the time has elapsed and gently fold in the 1.0 lb (453.6g) of cooked shrimps and the 2.0 tbsp (7.6g / 0.27 oz) of minced parsley.
5. Increase the slow cooker setting to high heat and cook for an additional 10.0 minutes to allow the shrimps to heat through and absorb the flavors of the marinara.
6. Portion the dish into five servings and garnish each with the grated Parmesan cheese before serving immediately.

Pro Tips for the Best Shrimp in Marinara Sauce

1. Avoid Rubbery Seafood: Since the recipe calls for pre-cooked shrimp, the 10-minute high-heat window is strictly for warming them through. Adding them too early in the slow-cooking process will result in a tough, rubbery texture that detracts from the gourmet feel of the dish.
2. Quality of Tomatoes Matters: Because the marinara is the base of the entire dish, use "San Marzano" style crushed tomatoes if possible. Their lower acidity and natural sweetness create a much richer sauce without needing added sugars.
3. The Fresh Herb Finish: Always add the minced parsley at the very end with the shrimp. Fresh herbs lose their vibrant color and essential oils when subjected to 5 hours of heat; adding them late preserves that "fresh from the kitchen" aroma.
4. Emulsify the Oil: Before starting the slow cooker, ensure you stir the avocado oil vigorously into the tomato and broth mixture. This helps create a smooth, consistent sauce texture rather than having oil droplets rise to the surface.

Frequently Asked Questions (FAQ)

1. Can I use raw shrimp instead of cooked shrimp for this recipe? Yes, you can substitute 1.0 lb (453.6g) of raw, peeled, and deveined shrimp. If using raw shrimp, add them during the final step and cook on the "High" setting for 15–20 minutes, or until they are pink and opaque throughout.

2. Is this Shrimp in Marinara Sauce keto-friendly? This recipe is naturally low-carb and fits well within a ketogenic lifestyle, containing approximately 6.6g (0.23 oz) of carbohydrates per serving. To keep the carb count as low as possible, ensure your crushed tomatoes have no added sugars or fillers.

3. What is the best way to serve this slow-cooked dish? For a traditional Italian experience, serve the Shrimp in Marinara Sauce over zoodles (zucchini noodles), spaghetti squash, or heart-of-palm pasta to keep it low-carb. If you aren't restricted by carbs, it pairs beautifully with al dente linguine or crusty sourdough bread.

4. How long can I store leftovers in the refrigerator? You can store any remaining portions in an airtight container for up to 2 days. When reheating, do so gently on the stovetop over low heat to prevent the shrimp from becoming overcooked and tough.

Pro Tips

• Add the pre-cooked shrimp only in the final 10-minute high-heat window. The sauce needs its long, slow simmer, but shrimp added early turn tough and rubbery.
• Use San Marzano-style crushed tomatoes if you can. Their lower acidity and natural sweetness build a richer sauce without any added sugar.
• Stir the avocado oil vigorously into the tomato and broth mixture before cooking. Emulsifying it up front keeps the sauce smooth instead of leaving oil droplets on the surface.
• Add the minced fresh parsley at the very end with the shrimp. Long heat would fade its color and strip its essential oils.
• Portion the finished dish into five servings and garnish each one with grated Parmesan right before serving.

Frequently Asked Questions

Can I use raw shrimp instead of cooked shrimp?

The recipe is built around pre-cooked shrimp warmed through in the last 10 minutes. Raw shrimp would need a different, longer cook and can easily go tough in the sauce.

Can I make the marinara sauce ahead of time?

Yes. The tomato base can be slow-cooked a day ahead and refrigerated. Reheat it, then fold in the shrimp and parsley at the very end.

Can I freeze the leftovers?

Freeze the marinara base on its own. Add fresh shrimp when you reheat it, since frozen-and-thawed shrimp lose their texture.

Is this shrimp marinara keto?

Each of the five servings has 6.6g of carbs and 23.7g of protein. The carbs come from the crushed tomatoes, which keep the sauce light enough for keto.
