❤️ WHY YOU WILL LOVE THIS LASAGNA
- Gut-Friendly: Designed specifically for individuals following a low FODMAP diet, this lasagna minimizes ingredients that commonly trigger digestive discomfort.
- Dairy-Free: This recipe uses lactose-free ingredients; however, it also offers low-FODMAP dairy-free alternatives for people who follow both low-FODMAP and dairy-free diets.
- Flavorful and Satisfying: Despite the dietary modifications, this lasagna boasts rich flavors from a hearty ragù and creamy béchamel sauce, ensuring a satisfying meal.
🍅 INGREDIENTS & SUBSTITUTES
FOR THE RAGÙ:
- Garlic-Infused Olive Oil: Provides the desired garlic flavor without the high FODMAP content found in whole garlic cloves.
- Carrots: Add natural sweetness and texture to the sauce.
- Minced Meat: A combination of meats works best as it offers depths of flavor; however, you can also use only beef, pork, or even minced chicken or turkey.
- Red Wine: Enhances the sauce's richness but can be omitted if preferred.
- Beef Stock or Water: I recommend using beef stock for the best flavor; however you can also use vegetable or chicken stock. You can substitute the stocks with water, however, you will lose a bit of the flavor and you may need to adjust the seasoning.
- Fresh Tomatoes: freshness and acidity to the ragù.
- Tomato Passata: Offers a smooth tomato base; canned diced tomatoes can be used as an alternative.
- Fresh Basil: Imparts aromatic herbal notes.
- Spring Onions: Provide a mild onion flavor without high FODMAP content; chives can be used as a substitute.
- Italian Herb Mix: Blend herbs like oregano, thyme, and rosemary to enhance the sauce's complexity.
- Salt and Black Pepper: To season according to taste.
For the Béchamel Sauce:
- Butter: Serves as the base fat for the sauce.
- Gluten-Free Flour: Thickens the béchamel while keeping it gluten-free.
- Lactose-Free Milk: Creates a creamy consistency without lactose; plant-based milk like almond or soy can be used as dairy-free alternatives.
- Nutmeg: Brings a warm, rich depth to the sauce.
- Salt and Black Pepper: To season according to taste.
For the Lasagna:
- Gluten-Free Lasagna Sheets: Ensure the dish remains suitable for those with gluten sensitivities.
- Grated Mozzarella: Opt for lactose-free or dairy-free mozzarella alternatives.
- Freshly Grated Parmesan Cheese: Lactose-free or dairy-free Parmesan-style cheeses can be used.
🔖 Low FODMAP Notes
- Garlic-Infused Olive Oil. Fresh garlic is high in FODMAPs, the only safe way to infuse your dish with garlic flavor is to use garlic-infused olive oil. Garlic is high in fructans and fructans are water soluble but not oil soluble, which means they don't leach out to the oil. Just make sure that the oil you buy doesn't contain any garlic pieces. My favorite is Garlic Infused Olive oil by Fody Foods.
- Tomatoes. According to Monash University Tomatoes are low FODMAP only 65g per serving(or about one-half of a medium-sized tomato). This lasagna uses 3 tomatoes but it serves 6, which means there is half a tomato per serving.
- Tomato Passata. The low FODMAP amount for tomato passata according to Monash University App is 72g per serving. This recipe uses 400ml and serves 6.
- Beef Stock. Make sure to use beef stock that is low FODMAP or to check that there are no high FODMAP ingredients.
- Spring Onions. Only the green parts of spring onions are low FODMAP.
- Italian Herb Mix. make sure to check that the mix doesn't contain any fodmap ingredients like onion or garlic.
- Gluten-free Flour. A low FODMAP diet doesn't mean you have to eat gluten-free, however, it is important to note that wheat flour is high in FODMAP. To learn more about which flours are low FODMAP, I recommend checking out this complete guide. When choosing gluten-free flour make sure that the blend doesn't contain any high FODMAP flours.
- Lactose-free milk. If you decide to use dairy-free milk make sure to use low FODMAP dairy-free milk like for example almond milk.
- Both Mozzarella and Parmesan Cheese are low FODMAP.
👩🏻🍳 How to Make This Lasagna
Step 1- Make the Ragù Sauce
Heat a large pot over medium heat. Once hot, add garlic-infused olive oil, minced meat, and diced carrots. Cook for a few minutes until the meat is mostly browned. Pour the red wine and let it simmer over high heat for a minute or two, allowing the alcohol to cook off. Add the beef stock (or water) and let it simmer for 5 to 8 minutes, or until the liquid has mostly evaporated.
Next, add the chopped tomatoes the tomato passata, chopped basil, and spring onions.
Season with the Italian herb mix, salt, and black pepper. Let it simmer over low heat for about 10 to 15 min. (The ragù sauce shouldn't be too liquid)
Step 2- Make the Béchamel Sauce
While the ragù sauce cooks, start preparing the béchamel sauce.
Melt the butter in a heavy-bottomed saucepan over medium heat. Stir in the flour and cook, stirring constantly, until the mixture bubbles slightly but doesn’t brown—about 2 minutes. Gradually add the hot milk, stirring continuously as the sauce thickens. Bring it to a gentle boil, then season with salt and pepper to taste. Reduce the heat and continue stirring for another 2 to 3 minutes until smooth.
Step 3- Assemble the Lasagna
Preheat your oven to 350°F.
Once both the béchamel and the ragù sauce are done, you can start assembling your lasagna. Start assembling the lasagna in a 7x9-inch baking dish. Start with a layer of ragù sauce, followed by a layer of lasagna sheets. Next, add more ragù sauce, a layer of béchamel sauce, and a sprinkle of grated mozzarella Place another layer of lasagna sheets on top and repeat the process until all the ingredients are used up. Finish with a final layer of ragù sauce and a generous topping of mozzarella and parmesan cheese.
Place it in the oven and bake for 30 to 35 minutes at 375 ℉. Or until the top is golden. Sprinkle some fresh basil and serve while it is warm.
🌟 Expert Tips
- Perfecting the Ragù: Allow the sauce to simmer gently to meld flavors and achieve a rich, hearty consistency.
- Béchamel Consistency: Whisk continuously while adding milk to the roux to prevent lumps and ensure a smooth sauce.
- Layering Technique: Start with a thin layer of ragù at the bottom of your baking dish to prevent the pasta from sticking. Alternate layers of pasta, ragù, béchamel, and cheese, finishing with a generous topping of cheese for a golden crust.
- Resting Period: After baking, let the lasagna rest for about 10-15 minutes. This allows it to set, making slicing and serving easier.
📖 Storage Guide
- Refrigeration: Once cooled, cover the lasagna tightly with plastic wrap or transfer it to an airtight container.
- Freezing: For longer storage, portion the lasagna into individual servings, wrap each piece in plastic wrap, and place them in freezer-safe bags or containers. Freeze for up to 3 months.
- Reheating: Preheat the oven to 180°C (350°F) before reheating. Place the lasagna in an oven-safe dish, cover with foil to retain moisture, and bake until heated through approximately 20-25 minutes. If reheating from frozen, it's advisable to thaw the lasagna in the refrigerator overnight before baking.

I haven't tried this yet, but it'd be helpful if you mentioned what size pan to use for baking, and some key nutritional facts for people with IBS, such as how much fiber per serving. Also, I live in the US, so cups and Fahrenheit would be nice! Looks delicious!
Gluten Free Stories says
Hi, Kelly. Thank you for the tips. All of my newer recipes have both the US cups and Fahrenheit. I'm currently working on changing all of my older recipes and hopefully, in the near future I'll add the nutritional facts. The size of the pan is 8x8 inches. I'll update that in the recipe as well.

When you say lactose free milk I wonder if I can use a nut milk? Almond milk?
Stefani Weiss says
Hi Venessa, yes you can use nut milk.
