How to Make Spinach Beef Cannelloni – Step by Step

Step 1: Prepare the Cannelloni Sauce

1. Heat 1 tablespoon of olive oil in a large saucepan over medium-high heat. Add the minced garlic and chopped onion and cook until fragrant and softened, about 2 minutes.
2. If using, add the finely chopped carrot and celery and cook for about 5 more minutes until they begin to soften.
3. Stir in the canned crushed tomatoes, broth, thyme, oregano, salt, pepper, and chili flakes if using. Bring to a gentle simmer, reduce the heat, cover, and cook for 10 minutes to blend the flavors.
4. For a smooth sauce, briefly puree with an immersion blender, or leave it chunky if you prefer more texture. Set aside.

Step 2: Cook the Spinach Beef Filling

1. In a skillet, heat 1 tablespoon olive oil over medium-high heat. Sauté the garlic and onion for about 2 minutes.
2. Add the ground beef and break it up with a spoon. Cook until browned and cooked through.
3. Stir in the thawed, drained spinach, crumbled bouillon cube, Worcestershire sauce, and black pepper. Add 1 cup of the prepared sauce to moisten the mixture and cook for another 1–2 minutes. Remove from heat and let the filling cool slightly before filling the pasta tubes.

Step 3: Assemble the Cannelloni

1. Preheat the oven to 180°C (350°F). If desired, par-cook the cannelloni tubes for 3–4 minutes to ensure even cooking, then drain. Alternatively, use ready-to-stuff manicotti.
2. Spoon or pipe the beef-spinach filling into each cannelloni tube. Spread about 1¼ cups of the sauce over the bottom of a 9×13-inch baking dish. Arrange the filled tubes in a single layer, pour the remaining sauce evenly over them, and finish with the grated mozzarella.

Step 4: Bake

1. Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbling and golden and the pasta is tender.
2. Let rest 5–10 minutes before serving so the filling sets slightly and is easier to slice and serve.

Helpful Tips and Cooking Techniques

• Use fresh mozzarella for the best melt and flavor; you can combine with a little grated Parmesan for extra depth.
• If you prefer more heat, increase the chili flakes in the sauce or add a pinch of red pepper flakes to the filling.
• To save time, substitute a good-quality store-bought marinara for the homemade sauce and adjust seasoning as needed.
• Filling the tubes is easiest with a piping bag or a resealable plastic bag with a corner snipped off. A small spoon also works.
• For consistent baking, place the dish on the middle oven rack and ensure the sauce covers the pasta so it steams and cooks through rather than drying out.

Serving Suggestions

Serve cannelloni with a crisp green salad dressed with balsamic vinaigrette and warm garlic bread or a rustic Italian loaf. A light red wine complements the richness, but non-alcoholic sparkling water with lemon also pairs nicely.

Storage and Leftovers

Refrigerate leftovers in an airtight container for up to 3 days. For longer storage, freeze portions for up to 3 months. To reheat from frozen, thaw overnight in the refrigerator and bake at 180°C (350°F) for about 20 minutes or until heated through; if reheating refrigerated portions, warm at 180°C (350°F) for 15–20 minutes.

Frequently Asked Questions (FAQs)

1. Can I make this dish ahead of time?

Yes. Assemble the cannelloni, cover the dish, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if baking straight from cold.

2. Can I substitute the beef with another protein?

Absolutely. Ground turkey, chicken, or a plant-based ground meat substitute work well. For a vegetarian version, use crumbled firm tofu, cooked lentils, or a mix of sautéed mushrooms and nuts.

3. How do I prevent the cannelloni from drying out?

Make sure there is enough sauce to cover the tubes during baking. The pasta absorbs moisture as it cooks, so a generous layer of sauce on the bottom and top keeps the filling moist.

4. Is there a gluten-free option?

Yes. Use gluten-free cannelloni or manicotti tubes and check that all other packaged ingredients (broth, bouillon) are labeled gluten-free.
