Notes

Nutrition Information
- Heat the olive oil in your pot over medium heat. Add the diced onion and cook for 3-4 minutes, until it’s soft and translucent.
- Add the minced garlic, oregano, and red pepper flakes. Cook for just 1 minute until fragrant. Don’t let the garlic burn!
- Pour in the broth, marinara sauce, and the can of fire-roasted tomatoes (with their juices). Give it a good stir and bring it to a gentle simmer.
- While the soup simmers, mix your ricotta and Parmesan cheese in a small bowl. Season it with a pinch of salt and pepper. This is your creamy lasagna layer.
- Add the raw shrimp to the simmering soup. Cook for 3-4 minutes. They cook fast! They’re done when pink and opaque.
- Now, stir in the zucchini noodles. They only need 2-3 minutes to soften slightly. We want them to have a bit of bite, not be mushy.
- Turn off the heat. It’s time for the magic. Drop spoonfuls of the ricotta mixture right into the hot soup. Don’t stir it in completely.
- Sprinkle the shredded mozzarella over the top. Pop a lid on the pot for 2-3 minutes to let the cheese melt beautifully.
- Ladle the soup into bowls, making sure everyone gets some of that creamy ricotta and melted mozzarella. Garnish with fresh basil and extra Parmesan. Dinner is served!
What to Serve With This Dish
This soup is a full meal in a bowl. But if you want to round it out, keep it simple and fast.
A big, crisp green salad with a lemon vinaigrette is perfect. So is a slice of garlic bread for the non-low-carb folks at your table.
For a keto-friendly side, try some quick roasted asparagus or broccoli. Toss them in oil, salt, and pepper, and roast at 400°F while the soup cooks.
Make This Recipe Your Own (Quick Swaps)
Make this work for you! Got chicken instead of shrimp? Use it. Need it dairy-free? No problem.
Protein Swap: Use diced cooked chicken sausage or shredded rotisserie chicken instead of shrimp. Add it with the broth to heat through.
Dairy-Free: Skip the ricotta and mozzarella. Use a dollop of plain, unsweetened coconut cream for richness and a dairy-free cheese shred on top.
Veggie Boost: Add a handful of fresh spinach or chopped kale with the zucchini noodles. It wilts right in.
How to Store Leftovers (If You Have Any!)
This soup stores great! Let it cool completely, then transfer it to an airtight container.
It will keep in the fridge for up to 3 days. Reheat it gently on the stove over medium-low heat. Add a splash of broth if it gets too thick.
I don’t recommend freezing it, as the zucchini noodles can become watery when thawed. It’s so good, you probably won’t have leftovers anyway!

FREQUENTLY ASKED QUESTIONS
Can I use pre-cooked shrimp?
Yes! Add them in the last 2 minutes of cooking, just to heat through. This prevents them from getting rubbery.
My zucchini noodles got soggy. What happened?
You cooked them too long. Add them at the very end, right before you turn off the heat. The residual heat is enough to soften them perfectly.
Is this soup keto-friendly?
Absolutely! With about 14g net carbs per serving, it fits perfectly into a standard keto meal plan. Just check your marinara sauce for added sugar.
