Lupin flour has a mild, toasted-bean character and a subtle almond note; paired with eggs and a touch of olive oil it produces a pasta that feels substantial rather than delicate, with a clean, savory backbone that complements both bright herb sauces and richer cream or mushroom preparations. What makes this version work is intentional simplicity — xanthan gum supplies the missing stretch gluten would normally provide, brief kneading prevents gummy overworking, and a short rest lets the lupin hydrate so sheets roll without tearing. Dusting with lupin flour or semolina and letting the cut nests dry slightly prevents sticking and helps the strands keep their shape in the pot. This recipe is for cooks who want homemade texture and a protein-forward, lower-carb alternative to wheat pasta, but also for anyone curious to work with a legume flour that rewards careful handling with sturdy, flavorful tagliatelle. ## Recipe Information - Prep Time: 35 minutes - Cook Time: 4 minutes - Total Time: 39 minutes - Servings: 2 - Difficulty: Medium - Category: Stovetop ## Ingredients ### Combine dry ingredients and make the well - 1 1/2 cups Lupin flour - 1 teaspoon Xanthan gum - 3 large Large eggs - 1 tablespoon Extra-virgin olive oil - 1 teaspoon Fine salt ### Add eggs and oil, form initial dough - 2 tablespoons Cold water (add gradually only if needed) ### Roll and cut into tagliatelle - 1/4 cup Lupin flour or semolina for dusting ## Instructions ### 1. Combine dry ingredients and make the well Whisk lupin flour, xanthan gum, and salt together in a large bowl to ensure even distribution of the binder and seasoning. Create a wide well in the center so the wet ingredients can be added without spilling. ### 2. Add eggs and oil, form initial dough Crack the eggs into the well, add the olive oil, and use a fork to slowly incorporate the flour from the inner edge until a shaggy dough forms. If the mixture feels overly dry and crumbly, add cold water 1 teaspoon at a time (up to the indicated amount) until the dough just comes together. ### 3. Knead briefly and rest Turn the dough out onto a lightly dusted surface and knead gently for 2–3 minutes until smooth and cohesive — lupin dough requires far less kneading than wheat dough. Wrap tightly in plastic or place under a bowl and rest for 15–20 minutes to allow the flour to hydrate and the xanthan to relax, which improves rollability. ### 4. Roll and cut into tagliatelle Divide the rested dough into 2 or 3 pieces and roll each piece out on a lightly dusted surface (with lupin flour or semolina) to about 1.5–2 mm thickness; keep unused pieces covered. Dust with additional flour, loosely roll up and slice into 6–8 mm ribbons, then unroll and toss gently to separate; alternatively use a pasta machine on a low setting to avoid tearing. ### 5. Dry slightly before cooking Let the cut tagliatelle rest on trays or a floured board for 10–15 minutes to firm up — this reduces the chance of sticking and loss of shape when added to boiling water. If not cooking immediately, hang strands briefly or lay them in nested nests on parchment and refrigerate for up to 2 hours. ### 6. Cook in rapidly boiling salted water and serve Bring a large pot of well-salted water to a vigorous boil and add the tagliatelle in small batches; fresh lupin pasta cooks quickly, about 2–4 minutes depending on thickness — test a strand for desired bite. Drain well, reserve a little pasta water to adjust sauce if needed, and finish the noodles in your sauce over low heat for 30–60 seconds before serving. ## Nutrition Estimated nutrition per serving (about ¾ cup): - Calories: 107 kcal - Protein: 8 g - Carbohydrates: 3 g - Fat: 6.9 g - Saturated Fat: 1 g - Trans Fat: 0 g - Fiber: 0 g - Sugar: 0.8 g - Added Sugars: 0 g - Cholesterol: 0 mg - Sodium: 969 mg - Potassium: 0 mg - Calcium: 1 mg - Iron: 0 mg - Vitamin D: 0 mcg ## Tips ### Weigh your flour Lupin flour compacts differently than wheat; use a scale or spoon-and-level the cup to keep hydration consistent and avoid a dry, crumbly dough. ### Distribute xanthan evenly Whisk xanthan with the flour before adding eggs so it hydrates uniformly and prevents gummy spots that make rolling difficult. ### Short knead, longer rest Knead just until cohesive — 2–3 minutes — then rest 15–20 minutes to let the lupin fully hydrate and the xanthan relax for easier rolling. ### Dust with semolina Use semolina or extra lupin flour when rolling and cutting to reduce sticking; semolina’s coarse texture gives strands a toothy surface that sauces cling to. ### Cook in small batches Fresh lupin pasta releases starch quickly; add a few nests at a time to a roaring boil and test at 2 minutes for doneness to avoid overcooking. ## Variations and Substitutions ### Blend with chickpea flour Replace up to 25% of the lupin flour with chickpea flour to mellow lupin’s bean note and increase elasticity while keeping protein content high. ### Spinach or herb tagliatelle Puree 1 packed cup of blanched spinach or basil with the eggs and use the same wet weight to add color and a fresh herb flavor without altering hydration much. ### Semolina-amplified dough For a firmer, more pasta-like bite, replace 20–30% of lupin flour with durum semolina; this adds structure and a familiar chew while keeping lupin prominent. ### Vegan adaptation Whisk 1/4 cup aquafaba plus 3 tbsp olive oil and increase xanthan to 1 1/4 teaspoons as a starting point; expect a different texture and slightly longer resting time. ## Notes ### Storage and Make-Ahead Cooked lupin tagliatelle keeps in an airtight container in the refrigerator for up to 3 days; toss with a little olive oil to prevent sticking and store sauce separately if possible. Uncooked cut nests can be refrigerated for 24 hours or frozen on a tray for up to 2 months, then transferred to a bag; cook from frozen adding an extra 30–60 seconds to the boiling time. Reheat cooked pasta by gently finishing it in a warm sauce for 30–60 seconds or plunge briefly into boiling water to refresh before saucing. ### Serving Suggestions Lupin tagliatelle shines with both bright and hearty accompaniments — try it tossed with lemon, garlic, anchovy and plenty of chopped parsley for a lively contrast, or finish it with a mushroom and crème fraîche sauce for a more substantial plate. Serve with a simple green salad (arugula with shaved fennel and lemon vinaigrette) and crusty bread if you like; pair with a crisp white like Vermentino or a light-bodied red such as Barbera for meatier sauces. ## Frequently Asked Questions ### Is lupin flour gluten-free? Yes, lupin flour is naturally gluten-free, but it’s a legume and often milled on shared equipment, so check packaging if you need certified gluten-free for celiac disease. ### Can I omit the xanthan gum? Xanthan replaces the elastic properties of gluten and helps lupin dough hold together; omitting it will likely produce a crumbly, fragile pasta unless you substitute with another binder like psyllium husk or increase egg yolks. ### Why is my dough crumbly or falls apart? Crumbly dough usually means under-hydration — add cold water 1 teaspoon at a time until it comes together, and ensure you mixed the xanthan evenly so it can bind properly. ### How long should I cook the noodles? Fresh lupin tagliatelle cooks quickly, typically 2–4 minutes depending on thickness; test a strand at 2 minutes and remember they’ll finish in the sauce for best texture. ### Are there allergy concerns with lupin? Yes — lupin can cause allergic reactions in people with peanut or other legume allergies, so avoid if you have those sensitivities and clearly note it when serving others. ## Related Recipes and Guides - [One-Pot Beef Bolognese](https://www.topshelf.recipes/recipes/one-pot-beef-bolognese) - [Stovetop Dutch-Oven Herb-Crusted Beef Roast with Pan Gravy](https://www.topshelf.recipes/recipes/stovetop-dutch-oven-herb-crusted-beef-roast-pan-gravy) - [Dubai Tacos](https://www.topshelf.recipes/recipes/dubai-tacos-stovetop-shawarma-style) - [Italian-Style Pot Roast with Tomatoes Olives and Fresh Herbs](https://www.topshelf.recipes/recipes/italian-style-pot-roast-tomatoes-olives-herbs-stovetop) - [Labor Day Grilled Lobster Rolls with Charred Scallion Brown Butter & Lemon‑Herb Aioli](https://www.topshelf.recipes/recipes/labour-day-grilled-lobster-rolls-charred-scallion-brown-butter-lemon-herb-aioli) - [Hainanese Chicken Rice](https://www.topshelf.recipes/recipes/hainanese-chicken-rice-stovetop) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan) - [Low-Fat Grill Swaps for Big Flavor](https://www.topshelf.recipes/articles/low-fat-grill-swaps-big-flavor) - [DIY Edible Monster Eyes Candy](https://www.topshelf.recipes/articles/diy-edible-monster-eyes-candy)
